Procharger kit
Zr1 map
Customer purchased and installed Procharger kit then brought to me because it didnt run. Just did an datalog... Cyl Airmass as well as others look like a wave. Anyone run into this? I thought I remember reading somewhere that Procharger changed the maf location on the new kits. The maf is right before the tb on this setup.

Bump for some help!
I don't think that's an issue with the MAF positioning because the MAP values are also changing which tells me that its an actual load change. I would look at Throttle blade position during a run like that and be sure it stays open, but my guess is its something like a belt slip or recirculation valve flutter. Maybe trans, but something is loading and unloading the engine.
looks like belt slip
Tightened the recirc valve and belt. Still running into the same similar problem. Everything is good until about 4 psi/ 4100 rpm and the same happens.Quote:
