Hear they are 180 HP and 360 TRQ programmer. Also dogear and tire changes. Anyone try one and if so how does it compare to other tunes?

It does increase HP but not near what they claim. My baseline was 241 RWHP (stock). Added the Hot Xcel tune and put down 385 RWHP. Thinking of selling it privately cause PPE would not refund my money. Very disappaointed in them. Poor business practices. Because of this, I am going to speak out every chance I get!

In my opinion, TTS Extreme is the best!

car stereo shop at best

This seems to be a recurring situation with this vendor.

And SDAVER you are correct, they are a car stereo shop over by Cal State University, Fullerton. They have been there for a long time. Not sure what they are doing in the performance diesel business? Never paid much attention to them before. But on a recent trip to a Home Depot nearby, I did notice they appeared to have a side entrance where possible a dyno was located? Diesel performance is definetly not the focus of the business.

All There Hp And Tq Numbers Are At The Crank Not To The Ground. And they do have a dyno there. I had there hot xcellerator on my lb7 and i did not like i got rid of it also. i think the only thing they have done good so far is make that little black box for an lly so u could run turbo back exhaust and trip no codes. i have it on my new truck and no problems, no check engine light. KNOCK ON WOOD

I have heard the negative feedback from them, but decided to give them a try anyway. To this day, the Hot Xcelerator/Enforcer stack has the best track times on my LLY. 14.25 @ 94 mph. Driveability is also good with no bucking, sputtering, bursting, etc.

The LLY PPE stack is not bad. No, it doesn't make advertised power to the tires, but it is NOT slow either. So far it has been the highest stack I've seen on my truck so far, but not higher than stacks I've seen on other trucks.

When I tested it, I blamed it for poor track performance stacked. I have found that it is not necessarily the stack, but my truck's fueling limits that are causing the trouble.

I dynoed 434, spinning my tires on the Dyno,i dont know if it could have been more or not? that was with their Hot and Enforcer Stack. I Run 13.9 in 1/4 with bad 60 ft times, i know the truck will do 13.80s once i resolve my traction issues.

I have a hot VA box stacked with the xcellerator and duramaximizer and it works great set on race, not extreme. 13.3 at mile high on #2. :ro) Add some drugs and she's 12's:D
