need some advice

[stang9150]

I have a 91 hatchback with a 331.The motor has afr 185 heads,fti custom cam,performer intake,bbk cold air kit ,stock mass air and stock injectors.The car dyno at 290 hp 335 ft lbs.The motor feels great on the street and mantains 300 ft lbs from 2700rpm up to 5200 where it all starts falling off.Iam using the stock maf and injectors due to wanting the car up and running i know i should be at least 30lbs injectors.What should i do about the intake i think that maybe a big bottle neck right now and why power falls off after 5000.The performer worked good on my mild 302 so on it went to get running.Any suggestions on what intake to run?The car has a tko-600 and 373 gears also.thanks for any input.

you need injectors first. Then worry about the intake.

If you have an FTI cam, then call ed. The perfect intake will correspond to the specs on his cam. He can tell you what you should get.

Go with an MAF and injectors first.
