Default 9-5 aero mAir not meeting mReq

I have a jzw stage 1 9-5 aero and my mAir does not meet the mReq. It is usually around 1280 and my mAir may spike to about 1150-1200 but its usually around 1100. I have a new MAF, DIC, plugs (ngk 7's), BPC/APC valve, forge bypass valve, and bolt mod. Ive checked for boost leaks and it will hit fuel cut with the w hose removed. The only thing else i can think of is wastegate. Any thoughts?

well the weird part is that when it spikes to 1150-1200 its usually around 4500 down low it feels like it builds boost fairly slowly. The car barley spins tires in 1st and doesn't at all in 2nd, when i first got the tune it would very easily spin tires in 2nd and spike to about 1300

Probably just adapting to your driving. Pull the ecu fuse, whatever number that is, and it should be back to how it was when you first put the tune in.

If you suspect the wastegate you could try and add a helper spring.

I got a spring from home depot and installed it. I worked for the most part. At the low end it sometimes spikes to 1400 but then goes down to about 1100 by 3500 and then soon after from about 3700-4700 its a consistent 1250. Other times though it will spike to 1300 and stay at 1250 for a good amount of time. Also in the high rpm i noticed some misfiring.
