Well...it still runs like **** anytime the MAF is plugged in, regardless if the pipe is straight or has bends. At this point I’m kind of at a loss. Did I really get a DOA MAF? This stupid thing is brand new out of the box Delphi AF10043.

Going to try a few more changes to the CAI setup, but if I am not able to get it calibrated via HPTuners then I’m just going to go back to the stock MAF and drill a hole in my intake tube to put a IAT sensor in. If I would have known converting to the LS2/6 “5 wire” style MAF was this much of a PITA I wouldn’t have done it.

 

Wanted to stop back by, and close this mystery out, in case anyone else has a similar issue. Turns out that the ECM voltage was low, and that was causing the erratic behavior when the MAF was plugged in. As soon as I fixed the low system voltage issue everything worked with the MAF. I know voltage issues can cause weird problems, but this one really had me stumped for a bit.
