Watch the STFT's. Adjust as needed. Mine was really rich when I first put the 80's in. Enough to have raw gas dripping from the plug when I pulled it out. I think I had to pull 20 or 25% just to get it to idle.

Having a issue with bank1 lean and bank 2 rich what would cause that?my tuner said its a mechanical issue would the header leak on bank 1 so cause it? Also my bov is not staying open in vacuum it flutters

Im having the same problems, same MAF blow through, but with 60's. My tuner also said it was a mechanical issue but I dont believe it. be interesting to see what you guys have to say. My STFT never move off of 1??

hard to say without a datalog. IF you're in open loop then stft's won't tell you shit. Who set up the base tune? It sounds to me like your base tune is just really far off. fix your exhaust leak first then datalog.

Justin at vmptuning did base tune. I did datalog and bank 1 was .75 and bank 2 was 1.25

you're not in open loop per your STFT- fix your exhaust leak first. then your need to see if your 02's are still working properly because if they're not then obviously they're telling the ecu the wrong things.

might also help to know where the maf and bov are located.

I dont believe car was warmed up all the way.my bov is right after blower before intercooler my maf is right before throttle body.
