Hello. I have an 02 z71 and did a 6.0 swap with ls3 heads and l92 intake. I had it dyno tuned as it had a 4.8 in it before. Well now I'm having a problem with the maf. It keeps popping up the p0101 code. I replaced both the maf and map sensors, but the problem is still there and the code keeps comin back. It acts like its cutting fuel.
What its doin is when you start to accelerate and the engine starts to get around 1800-2000rpms it bogs down for a monent. Sounds like its popping into the intake. After it catches itself it does fine, but when your cruising and start to accelerate; it does it again. If you flat foot it, it does just fine. Sometimes it isles high. Almost 1800 at times. There doesn't seem to be any vacuum leaks that I can find. Any help is much appreciated

 

No one have an idea?
