westers dyno results
Well went to the dyno today, Imust say I am pleased with the results.
with stock pcm 246.23 rwhp 299.74 rwtq
with westers pcm 273.38 rwhp 335.06 rwtq
gain over stock 27.15 rwhp 35.32 rwtq
If you figure 26 percent driveline loss with the allison tranny
stock 246.23 rwhp + 26% = 332.74 at the crank
westers 273.38 rwhp + 26% = 369.43 at the crank
h.p. gain at the crank 36.69 not to bad
The only other mod done on the truck performance wise is an Airaid filter kit
as you can see on the stock dyno run the torque had a bad spike on pull two so I did not use the toque from that pull we did do several more pulls just to make sure it was a spike and it was, all pulls on the stock pcm netted 299 to 301 rwtq
The westers pcm had approx. 750 miles on it when dynoed
I pulled it in, dynoed it with the westers two pulls then swapped out the pcm's and did two pulls on the stock pcm.
westers 93 hot tune

which numbers reflect the intake? both before and afters? or was this filter kit added at the same time the tune was?

I wonder why your truck dynoed so low, my truck with just exhaust put down 240hp and 352 tq. Granted I have the 4l80 and you have the allision but the numbers shouldnt be that far off.
