Hey Guys, I'm new with the program, and I can't find much on my 04 2500 silverado ! I'm looking to increase the horsepower and torque, I've uploaded my stock file of my truck only thing that has been changed was the speed limiter. Any help would be greatly appreciated.
Thanks!
Happiness consists of wanting the right things, goes
the saying.
All you can do by tuning, is remove nonidealities. You
can expect not much torque improvement generally
until you increase the air mass in-taken, and the
efficiency of the burn.
The tune repository is a great learning opportunity,
you will find truck tunes to study and some of them
will purport certain results and "done-ness" making
them worth the while. Use your "compare" function
to see what people have touched, and then you can
focus on why.
Now trucks do have some unusually nonideal "stuff"
in their factory setup -
- PE mode is held off too long, in pursuit of towing
fuel economy
- low spark advance, to support this
- aggressive burst knock retard making for poor throttle
response and low first gear acceleration
- the usual cat overtemp protection to hose down your
WOT fueling, laid over a too-rich PE table (check the EQ
vs ECT vs MAP as well, and other modal enrichments;
fat is safe but fat is no damn good in the sprint).
These tend to dog you more on the street / track, than
on the rollers; you might never even see them during a
3rd gear dyno pull from idle.
