unique pulsewidth tables for one. can tell it was a quick job. 120mpa/70mm3 and down, adjusted by certian % no blending. 120mpa and 4200pw? just sucks paying $1000 for a "custom" tune...

I have seen first hand the work come from walls. i could have just gotten the worst of the worst, and every time it is "employees screw up". just a bad taste in my mouth.

snow, Brian built Al's truck when Harry H owned it. a 7000 dollar allison... and a tune. Brents truck I tuned. Harrys new truck I built.

:eek: 4200pw?!?! :spit:

4200 pulse width?!?!? At what area of the map?? That is a totally unsafe pulse width by ANYONES standards at any point of opperation IMO. Got much diesel in your oil? :thumb: No wonder the CP3 wont hold rail pressure.

ok calm the f*** down. its going back to him when i get time. when i bought the truck it had bad injectors, and didnt even smoke. changed injectors, built trans, lift pump, sending unit, up pipes, down pipe, full exhaust, cold air, changed that shit manifold, the thing went pretty damn good for 100 hp tune, but after it was up'ed it didnt change much at all, and still zero smoke

lets make this clear, I do NOT run 4200pw. TQ asked what I thought was interesting about Walls tunes. I just stated what Ive seen in the past, from that shop. I know nothing about the truck in question. Im not sudjesting it is running 4200.
