Do you have a wideband in the car right now, or just going what the dyno o2 said?
I also assume your running your 17 lbs on a mix, or just 93? If you were tuned on the dyno at 25 psi, did the tuner map the rest of the boost levels as well?
yeah it mis fires under WOT on high w/ 6s after maybe 1-2 pulls but on low boost it mis fires on the other plugs when doing pulls and yes I'm running plx M300 self calibrating ..w/ a new sensor and yes was running mix on 17 psi... didn't mix til 14-15 psi just to be on the safe side he said..its a pretty safe tune which i believe ,just wanted a lil more ummmF for the event..I just didn't have the funds to go to richmond and have the norm. tuner tune it on Nep...Its a catch 22 honestly...I'm very pleased w/ how my car was tuned,I really don't know the full ethics of tuning or else it would of been done myself...but i watched everything he and the other tuner did and it seemed that under WOT all the way towards the top of the rpm range it richened out and he would go back and add and subtracted the % of fuel where needed in the rpm gain and did timing..so yes he mapped the boost levels i would say..i just don't understand why it did well on the dyno but here at home sux ...i was planning on running full 110 at the event to help but would like to get this issue solved 1st..no need if i can't go to high...right?
thanx for your help and positive feedback thus far...
