Going to Dyno
I will be dynoing next saturday my 1997 Z28 M6.
All i have done is a pulley. I am going to make a pass with the MAF screen in, then remove it, and make another pass to see if there are any gains. I will let you know. All of my other cars ran fine with no screen

You may want to make a few more runs..
You need to have 1 run where the car works on relearning values..
If the car freaks it can go into an open loop type of scenario and show you a gain but the next run would bring you back to no gain shown..
I found that same scenario when I installed a lid.. its first run was really high since I had to unplug the IAT and MAF but not sure why it did it.. it hasnt done it since.. but it did make a real good run with almost perfect A/F.. but that was just 1 time.. after that it went back to where it was supposed to be.
