high rpm hesitation
hey im pretty new at this i picked up a 93 r1 about 6 months ago and over the winter i put on a 3" greddy exhoust it all went on smoothly. except i had no place to hook up the egr so i just caped the hose and on the turbo manifold when i was bolting it in the cast iron peice thats threaded busted off on one of the bolts. witch i can get fixed when i do non seqential. i also cut out some of the bottom of the air box for more air flow. so i finnaly took it out for just a little test and when it was all nice and warm i gave it and noticed that at about 7000rpm i got a major hesitation almost like hitting the gov. but a bitt different and it back fires like crazy. i dfont know too too much about these engines but any help would be very usefull?

well, first off you desperately need some sort of restriction in your exhaust if you're on bone stock turbos. The stock wastegate can't accomodate that low backpressure. How do you know you're running stock boost pressure? I'm hoping you have a boost gauge of some sort. It's possible you're hitting fuel cut because you're over-boosting.
Do you have a plastic ast?
