This is most likely it.

I have an 11' 370z nismo with installed Stillen SC and oil cooler. I bought the canned tune from Stillen and for what it's worth I too have an occasional P0300 pop up. I want to make a few mods and then I hope to get it to a tuner soon which will hopefully fix the problems I'm having with the shitty Stillen SC kit.

I ordered some material for a shield... I'm going to make an attempt this week to get it done. I'll switch out the TB's as well. I just haven't had the time.

My last resort will be back to the tuners, but this will wait until the spring. I'm considering TopGunz A-A kit and would rather just put that on and re-tune. I have a true dual exhaust as well to install.

Having the MAFs so close to the filters is just a terrible design. You normally want them closer to the T.B's. Especially when there is a difference in Temperature. Maf's are reading directly after the filters... then goes through the charger and maybe not significant, the air temp/density is not the same. I have a feeling this initial design has something to do with their CARB certification.... as well as the crappy in house tune

I talked with someone that mentioned that this Stillen S.C. kit, if installed by a SAE certified tech at Nissan, will not void the factory warranty. Have to use the Stillen tune to stay CARB compliant
