I've got a couple buddies with duramax's, one is an LBZ with a bullydog and the other is an LMM with a custom tuned ECM(not sure where he sent it?) but both of their pickups will hang in gear and dont shift near as good as mine with the PPE, I know it has to do with their tuning. I've been kicking around the idea of switching to EFI DSP5 switch tuning, I'm just wondering if I will still have the awsome shifts with EFI as I do with PPE? I know it's possible to have the smooth shifting as I do know, I guess my question is who can get it done?

I'm sure any of the top EFI guys will have even better shifting than the PPE does, and at the very least they will be just a good.

Thats what I was thinking!

My truck is an LBZ so I dont know if I should compare, but I just switched from PPE to EFI and although my PPE shifted awesome the EFI tunes I'm running do shift a little better. I have a 1057 converter and with the PPE when it locked it was abrupt and the truck would jolt forward during the lockup. With the EFI tunes it is a good positive lock but its much smoother and doesn't feel harsh at all. Before it felt just like you shifted a stick shift to 5th gear and dumped the clutch, now it feels like it would feel if you let the clutch out easy. I hope this makes sense, kind of hard to explain.

mine doesn't feel harsh, from what i understand ppe doesn't change anything to do with converter lockup. Could be your engine is defueling with EFI as described by 2006GMCDuramax.

Im putn that same EFI setup on my truck today:D, and ill let ya know if it shifts any better than the quadzilla or ppe (a friend has the ppe on his truck)

It will shift much better than the quad, I hated how my Quad shifted. Never ran PPE, but my Edge Evo Race is awesome compared to the Quad. I'm leaning towards EFI and the switch now that it's out for the LMM as well. Chris

I'm pretty new to this stuff, so I have been asking a lot of Questions. From what I'm being told, there is nothing that can be done with the shiffting paramiters on an 09, don't quote me but this is what I have been told. I have a EFI Live w/ DPS5 on its way with DPF delete pipe. Banks runs great just love trying new stuff.

You dont have to make changes in the TCM to change the way the Ally shifts, Some tunes have perfect shifting characteristics and some are terrible.

Good info to know,

It is going to depend on how it is tuned but EFI Live will beat any of the others out there, bar none.

I don't like how EFI makes your engine rattle when you get in the throttle hard.... Besides, I don't agree, since I have outran some EFI trucks with my PPE...

Besides, I don't agree, since I have outran some EFI trucks with my PPE...Not knocking PPE, it has it's place and its a great programer, but you need to try an EFI tune from someone who knows what there doing. There are a few vendors on this site that write clean, strong, quiet, and efficient tunes.

The quad made mine shift lift crap. Know with EFI its shifts like butter:D

That rattling is ALL in the tune, not because its efi. And do you know what kind of tune those efi trucks were running? Just sayin they could be runnin a 60hp tune or somethin, My truck with a 150 tune is no joke for bein 7500lbs

One of the trucks I am speaking of was running a duramaxtuner.com tune, and I think the rattle also finally broke the piston....(could be rattle is not audible to some drivers) not sure if his tunes are one of the ones you mention are good, or not, of course there could be some good ones out there, after all EFI is just a tuner software therefore you really have to know what you are doing to not mess up engine....

The rattle is from the tuning for sure. PPE is a decent pre-canned tune but it cannot compete with the abilites of a well tuned EFI Live vehicle. I have out ran my buddies truck with the HOT 2 PLUS by at least 10 lengths in the quarter. It was hard for him to beleive that before hand.

my ppe 225 tune has real bad timing rattle when its cold out, not enough for me to worry about it once it gets above about 170º it stops. Those cold mornings when I get a fire call and I forget to plug the truck in it sounds like a 7.3 ford..... I am going to switch to efi live as soon as the funds allow for it.

wow , ive never been beat by EFI tuned truck that had same stock equipment like my truck

was your buddy's truck also equiped like your truck - with twin cp'3s, big turbo, ect...

i have started my truck 10 degrees below zero, and since nature of the beast, engine is noisier stock or with PPE...

may want to call PPE incase update is available for your truck....

I run tuning from Nick at duramaxtuner.com and could'nt be happier. Its been colder than hell here and mine does'nt rattle anymore than normal on a cold morning. All of my tunes are very quiet and clean and drive and shift like a stock truck till you get your foot in it then you relize its not stock. My tow tune, around 80 rwhp will get 20+ mpg in the summer and runs cool as hell with a load of 20k plus on the gooseneck and EGT's are always below 1000 degrees no matter what and usually run at 800 or less towing in 100 degree heat in the summer with the A/C crankin.

That's very cool. I might try EFI later this Spring to see the difference. I have ran PPE and currently have Edge Evo Race. I'm looking for some well balanced tunes and the DSP5 that EFI offers for the LMM is a nice addition that I want to try.

but both of their pickups will hang in gear and dont shift near as good as mine with the PPE, I know it has to do with their tuning.

This symptom indicates an inadequate fuel supply to the engine. Regardless of the tuning method, running out of fuel will cause this to happen. Your friends might try changing their fuel filters or switching to smaller tunes. :)

i got rid of my ppe becuase of the horrible shifting...i went with efi and its all good now..nicks the man:coolnana:

Horrible shifting...?:confused: My truck with PPE shifts way better than my buddies priviously mentioned EFI live tuning...

Yea the shifting with PPE is stock as could be, not harsh at all!

Apparently EFI is working on a fix to talk to the 09 TCM's (stabilitrak and traction control are the problem) Hopefully this summer we will see a release that will address our TCM's.

Mine is tuned, Trans is built and although it shifts good, it could be so much better..........................Come on EFI, hurry up!:)

The 09 TCM is an entirely new controller, so development needs to start from scratch. At this stage it's still several months away.

Here's a question Cindy (maybe you know). Could an 08 TCM be installed in my truck thereby getting around the known issues of efi not controlling it?

Given the code in the 09 is different to the 08, I doubt it would work.

I agree, a lift pump solved what I thought was a major defueling problem.

I've been kicking the idea of EFI Live but I'm not sure about it.I don't do any racing,I do some towing (24' enclosed with race car) I don't drive it hard but if I get ready I get down on it when I want to.But I sell tuners,exhaust,intake kits and I enjoy playing around with it.If were to get it I would by from a vendor and maybe by the DS switch deal.I would have to have some help with fixing my own tunes,I used to be a GM Parts Manager and me and the diesel tech are good friends,he is still there and they have a service writer that has EFI Live and he has played with some LS stuff.He talks about how cool it is.

So if I were to get it,it would be just something to tinker with and I don't know if I could spend the $$$ to do that.Unless I could sell a few things to offset the cost.I know some will say I'll be glad I did, but what do ya'll think?Being I'm not racing,I just what a good shifting trans with good more down low at somewhat part throttle.I think I would like but I don't know???

Thanks for any input
