jw33 Posted January 12, 2010 Share Posted January 12, 2010 What is the most boost you guys have seen, drove an 03 today that hit 39 psi, ran like no other truck ive ever drove, it was a trade in over the weekend, open hood and antifreeze was puking everywhere, the look on the used car managers face was priceless when i told him about it, serves the stupid fuckers rite.

Keith Browning Posted January 12, 2010 Share Posted January 12, 2010 Umm... 39 PSI is a little high. Current calibrations start doing things to slow the turbo and de-rate the engine approaching 26 PSI and even with a stock calibration and a stuck turbo I personally have never seen more than 30-32 PSI a few years ago with older calibrations. I would suspect a non-OEM calibration in this truck then I might test the turbo. Quote Link to comment Share on other sites More sharing options...
jw33 Posted January 12, 2010 Author Share Posted January 12, 2010 Turbo was most probally froze up,had the k&n filter,4 inch exhaust,so im sure it had a aftermarket tune in it,i guess it will become someone eles problem heading to the auction, that truck is the second one ive seen with that much boost, both were early 04s first blew the side of tank off the intercooler Quote Link to comment Share on other sites More sharing options...
Aaron Posted January 12, 2010 Share Posted January 12, 2010 Drove a truck a guy had a big (+310hp) tune on at the track, he uses it as a drag vehicle (no plates, rollcage, etc.) (at 8k lbs, don't ask me why), it was upwards of 65psi (6.4) Quote Link to comment Share on other sites More sharing options...
