I keep reading threads here about PCM ForLess
can gain you an additional 10 horse just by recalibrating the PCM and tuning some fuel tables on mildly-stock cars??? If anyone know exactly was is being changed and the tables it will be helpful.

DYNO: Bone stock w/ exception of Catback. 269rwhp/318rwtq (SAE Corrected)

Need to be installed:
CC305 Kit, 3.42 LS1 stock rearend, Hooker Coated Shorties 1-5/8, SLP Level 1 Susp. Pkg.
-------------------------

 

Stock would have a lot to gain by reducing the fuel to air PE tables. Getting them closer to 13 or 13.5 instead of 11.7 would help a lot I imagine.

he just adds a couple degrees of timing advance and claims 10 hp. its pretty much the same thing as the power tune with the hpp.

They should lean it out up top a bit, but its not safe to do that over mail order, since there is no way to know for sure how much they can do safely.

If you want to done right, do it yourself.
