Ever since I've been making little mods to my fc (88) nothing major into the motor just the outside of the motor. My FC is starting to wine real bad. after hitting 4k rpms the motor starts to lose around 85% of its power and it gets real loud as if its clogged and no gas is getting into the motor. After it passes 4k rpms sometimes it gets back to normal. Sometimes it doesnt even hesitate at 4k rpms. but id say 9 out of 10 times it hesitates. Ne1 know what my problem could be ?
Im guessing its the injectors, but I dont want to play the guessing game just yet.

Sounds like the secondary injectors arent coming online. Check all the grounds, and do a search for this problem in the 2nd gen tech section, its fairly common and there has been lots of info posted.
