What should a Stock 900 EFI Be running for Max RPM? Thank you.

Completely stock 900s should run ~7600 RPM

I was going to say 73-7400? Mine ran exactly 7300 stock after break in and 7400 with a can which I was told it would run after install. With other mods intake/reeds and such I am seeing 7600-7700. I thought this was over the stock powerband of the pipe? Idacat is this OK? Or should I add a gram or two of weight? Running between 3-6000ft doesn't make any difference road or deep snow. Currently running 74g weights and is a late '03 151
Thanks Mike

I like to see mine at about 7500-7600. They say the sock tach is normally about 150 - 200 low. So if you are seeing 7600 you are really spinning more like 7400.
