Im looking to turn up the horsepower in my 99' GMC CV200 with a CAT 3126. It has an AT545 but I plan to eventually upgrade it to an MT643 or 653 or a manual trans, but I'd rather just go for the MT. Currently it is set at 175 HP.
Is there anyway to turn up the horsepower without going to the CAT dealer and spending $500? Is it dealer specific software and override codes?
You will need someone with CAT ET, access to the sis website, and ECM recal tool. Then its still going to run you about 250 bucks to CAT. They charge you for a horse power increase, derate is free.
To do it without paying is extremely hard. Pretty much you have to have a good friend that works for the dealer. I was a field mechanic for Caterpillar and we couldn't even turn up our service truck with out a dealer supplied password from Cat. You basically pay for the password. Although if I remember right $500 sounds like a cheap price I want to say I thought it was around $1000
