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

 

Wester's sends you another programmed ECU? Can't remember but was curious about turn around and such...thx.

 

yeah i've got westers on mine, tell him your new mods and he sends the new one out, then you send the old one back.

 

Those numbers are very impressive.

 

Very nice gain ther eman,mine gained over 30rwhp and 35rwtq!Lyndon knows his stuff for damn dure!

 

how much did it run for the tune?

 

for your truck it should be 495.00 unless you get in on a group buy or something

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

 

the filter kit was added about a year ago so both of them have the added h.p. from the filter kit in them.

 

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.
