question

[rawfamily]

I just finished my sr20 install, and wanted to make sure the wiring was right so i started it. It idled fine but won't rev past 2500 rpms. i had the maf hooked up and disconnected and both ran the same, but not all the vac hoses or all the clamps tight. i have searched a little and " i could be maf " came up a lot. guess just wanting to mack sure i wired up the maf plug right. The plug didn't plug into the maf perfect so i modded it to fit? anyone else 's fit like shit? thanks for ur time.
