A friend just got a new 6.0 gasser and was wondering what programmer is the hot ticket right now? Any help?

Go with a mail order ecu tune you will get allot better results than a generic programmer tune. Try Westers or Nelson.

Wester's is the way to go. I had one in my 5.7 Yukon and it really woke the thing up. Best part is, Lyndon is more than happy to work with you on a custom tune. I plan on one for mine as soon as he's got the PCMs for the '05s.

Westers is the way to go for sure. Custom tuning will get you more power than any handheld will for sure. Just do a search for Westers Garage and you should find all kinds of info on the net...

Thanks for the help guys. I've passed the info along. Now he can flip a coin between Westers or Nelsons I guess.:)

I have heard positive results from Nelson's tunes. I don't have one and cannot comment from personal experience.

I do have a Wester's and am very pleased with the cost, the ease of install and the results.

I chose Wester's for several reasons:
With the Wester's you get;
1) incredible performance and throttle response
2) Increased gas mileage
3) Optimized 87 octane tuning
4) Nice firm shifting, as firm as you want!
5) Faster and earlier downshifting
6) up-gradeable for ANY mod for LIFETIME at no cost
7) Always have 30 days to test before sending core back
8) Fabulious and personal tech support
9) If you buy a new truck, Wester's will give a FULL credit
of your PCM cost toward the new one.

E-mail or call him to ask any questions, he's really easy and helpfull to talk to.

Wester’s Performance Tuning options


Wester's Performance tunes are now available with these basic choices.

1) 85 octane high altitude tune

2) Dual 87-91 Octane tune (will automatically adjusts for octane)

3) Dual 89-93 Octane tune (will automatically adjusts for octane)
(These dual octane tunes are recommended for all dual purpose (work/play) trucks.

4) 91 Octane HOT tune (much more aggressive than the Dual octane tune)
(Recommended for performance trucks where higher than 91 octane fuel isn’t available, like California.)

5) 93 Octane HOT tune (much more aggressive than the Dual octane tune)
(Recommended for performance trucks. No, or very limited, heavy towing or hauling!)

Of course he can custom tune any of the basic program tunes to your specific requirements and desires.

The new 87/91 and 89/93 dual fuel tunes will be able to run with 87 or 89 octane in MOST conditions with good performance, or with 89, 91 or 93 when even more performance is wanted. The dual octane tunes are capable of tuning for a higher octane. The factory tune will only advance the timing to the limits set in the original spark tables. Changing between 87 or 89 octane and 91 or 93 is automatic, the tuning will adjust itself for the octane you are using by referencing another spark table.

Under MOST conditions, all the tunes will run fine with the octane programmed for, but altitude, towing, load, condition of the engine, temperature, poor fuel quality, oxygenated fuels, or sensor variations may require choosing a higher octane. Just be aware that under certain conditions a higher octane fuel may be required, and that more performance and sometimes better fuel mileage is available just by using higher octane.
