Non MAF-less Tuning Simple hotcam in a '99 Fbody with M6. Changed the VE up to 1200 RPM and increased idle. Idle quality is decent and not much bucking. However, I'm getting code 102 and MAF doesn't even really read. Just hangs at .31. I know I'm running rich and probably need to do some work on the fuel trims but I'd rather not go SD.
What to do? HP Tuners is some powerful software but the learning curve is a bitch...
Any help would be appreciated.

Appears the MAF is dead or way low. Start with the basics,
reseat the connector, look for +12V on the pink wire and
+5V (or pretty close) on the yellow wire. If you have a DMM
that reads frequency idle should be throwing about 2500Hz.
