You pmed me about the maf but your PM's are off lol.

It's for the ford lightning maf, best used in a 3" pipe. I had mine in a 2.75 and maxed it out pretty fast.

The HPX maf's are supposed to be better if you get the programed with the Z32 curve on them. I might have posted the link from Zilvia on here if not you might be able to search it. The flange for that maf is right here.

I doubt ill pass 400hp I realistically only want 350 hp daily. currently my ic piping 2.5 in will the maf slide into that size pipe? ughhh the damn fitment game again lol. Yellow thanks for the reply brother! I appreciate it greatly!

The voltage the maf saw once I hit 7k rpm was around 4.X can't remember off the top of my head anymore. At the time I only made 398whp @ 18psi, Someone on the nistune forum told me it was prob maxing out sooner because it wasn't in a 3" pipe. The HPX mafs can be programed with the Z32 curve on the hardware itself and setup for what size pipe you have it in. Honestly I probably would have tried them out before I went to the AEM but I didn't find out about it till a few months after I bought the AEM.

I had my MAF N62 on a 3"pipe but it was less than 18" from the turbo so I made a cold air setup with a 2.5" 90° pipe to space it out but it still cuts. I'm switching to a 3" pipe for the extension tomorrow I just wasnt sure if it would need that and I didnt want to cut the 3" pipe I had. I matt at nistune suggested some settings to adjust to help my cut.

What your setup?

yeah man i'd have to say you were too close to the inlet of the turbo. I've seen people put the maf right on top of the inlet with a coupler and they have all kinds of probs getting the maf to read right. If you went blow thru it might help some. but they way you have it setup now that's a damn good distance. Watch your voltage when you rev out to 7 -8k rpm. Then you'll know if your maxing out the maf.
