PCMFORLESS Tune for 5.3L

[2004GMC1500CC]

Wondering what kind of performance/mpg gain I can expect for my 5.3L CC? Don't really plan on doing any other mods to it, but would like to get rid of the torque management and gain a little power and mileage. Want to keep using regular unleaded as well. Anybody got any real world results.

I don't know of any actual dyno #s, but the giuys I've talked to have been very happy w/ theirs. I'd advise against having all of the TM removed if you're not going to upgrade anything else. The tranny won't hold very long. I'd do 80% removed and put a cooler, billet servo, and shift kit on the trans. These 4L60Es are pretty weak, those mods will help it live having more power going through it.

I have an 01 Tahoe 5.3 and I am very happy with Brian's tune. I have the 93 octane tune, got rid of the slop in shifting, and locked out overdrive until 50mph. I gained 3 mpg city and highway. This has been a HUGE performance gain! Just tell Brian exactly what you want and I am sure you will be satisfied.

What is the cost/time involved in installing the cooler, billet servo, and shift kit on the trans. Im thinking about doing a 5.3 tune as well on my '03 but am in the same boat, dont want to do alot of other mods, but dont want to mess anything up either.

can those guys do a 6.0 as well? Can they program for a certain tire size too?

Bryan can do whatever you want!

I had the PCM forless tune for about 100miles on my 04 1500cc before I sent it back to get reprogramed (something with an error code issue).

I liked it while I had it and it hadnt even broken in yet.

I say it is a worthy investment.

I absolutely love my PCMforLess tune! I've never been one for calculating fuel economy, so unfortunately I don't have any solid numbers for you there. I can tell you this though, my truck really moves now, night and day from what it was. Bryan is an awesome guy too, great to deal with and he really knows his stuff.

Love mine too! Bryan is great to deal with!
