I have a dyno tuned diablo chip in my car. I ran it on the dynojet today at a seperate shop. Its running lean on the bottom and at about 3,800 rpms its at or around 13 to1 and keeps going lower. It eventually gets to the 12 to 1 area into the high 11's in the high rpm range. The car only put down 248 rwhp and 286 rwtq. It was heat soaked though. But before the dyno day I got 256 rwhp and 302 rwtq on the same dyno. I'm pretty much pissed about the tune though, last time we ran it we didn't do a wideband. So the a/f numbers were suprising. The car was tuned back in June of 03, no other hp mods have been added since. I am suppost to have a 13.5-13.7 a/f all the way across the board. The dyno I ran my car at this time was not the same people who tuned the car before.
