try using some injector cleaner...also, run the codes and see if anything comes up...it takes 30 seconds to check them. a tutorial at www.1300cc.com



also, i sort of had a similar problem like yours although mine would hit a wall at 7500. it would almost seem like my n/a would lean out or get too rich at that point. did it since the day i got it with a fresh rebuild.............until..........one day i got bumped in the rear by a mustang while i was sitting at a light...no damage at all, but it kind of shook the car. so after i got his insurance info i took off...and was pissed...so i floored it and redlined it. and whadda ya know?..........it hit 8500rpm and kept pulling!!!!!!!!!!! i was like HOLY ****! this it what its SUPPOSED to be like! it was so noticeably faster than it ever had been...



this lasted for about 2 months and then it slowly reverted back to its 7500 wall...and it still does this now. i dunno if the hit jarred something on the fuel pump...or knocked the filter on the fuel pump around...still can't figured it out...but i want it to go back to what it was!!!!!!!!!!!! haha

that is the VDI solenoid valve closing up...30 and 33...that is why you are lacking high rpm power...





a 12 year old fuel pump could be it too!
