Hello everyone.
VQ37, stock ecu tuned with ecutek
I had 3-inch intakes installed, which didn't perfectly fit my car (JDM vs USDM engine bay wiring, etc)
I was aware of the issue; however, I didn't think it was that big of a problem, so I went for a tune with the intakes that didnt fit well (as a place holder) ... presented no leaks or anything. Now, I've changed to a set of intakes that is made for my specific JDM model. The car is running ok, it struggles on idle and starts to stall out when I have the AC on. The only visible difference I can see from the two intakes are the total length of the piping and the MAF position with the new intakes having the MAF closer to the throttle body than the old set.
I'm not sure what is causing the issue, and regarding that, how should I be tweaking the maf curve? I can notice a torque dip around the 3-4k rpm range, but apart from that, it runs fair. Misfires sometimes, and on a cold start, it jumps to 2.6k rpm.
