First off, not my car. It is a 92 talon, b16g, 550's, gm maft, keydiver chip, 1G dejon IC and piping, ngk bpr7es at .028" gap, napa beldon plug wires.
It was running awesome on 18 lbs, just a tiny bit of boost creep, that's it. A couple of days ago it started stuttering under boost, like it is misfiring. It is more pronounced at WOT. The stuttering starts at varying boost pressures.
He was thinking boost leak, I said ignition, but we tested for leaks anyway. The only leak we found was at the J-pipe to turbo flange, but his gm maf is set up as blow through, so I still think ignition.
We are going to warranty his wires and get new plugs, fix the j-pipe leak, and clean his maf. I am thinking that I'm forgetting something though, any suggestions?
