I tried to get a tune, with 3 pulls. My best pull was 296 h.p. 356 tq. My A/F ratio is 10.5 and drops off even more after 4500. Its pinging like a bastard and is generally not running right. I'm obviously running WAY too rich, but they can't tune that out without a chip. The tech said my options are either to get a chip, in which he'll delete the egr functions and TRY to get my a/f ration round 11.55. For some reason he said i may still get pinging though, what's the deal with that? Or he said to go with 30lb. injectors and a new maf. What do you guys think i should do. Either way he said i should see atleast 30 more horses. If i can get my scanner to work right i'll post up the dyno sheet. Please help guys i need to get this done. thanks alot. By the way, apparantly i'm only seeing 4-5 lbs of boost, which IMO is bull****, cause it has a smaller pulley and upgraded impellar.
