i have been experiencing some hesitation while cruising on the highway and while accelerating in when there is high cylinder pressure, for example fifth gear going up a hill. its almost like the car burbs and then goes back to normal like nothing happened. its a built boosted B18C with 750cc injectors and msd ignition. i can provide more info if needed. any ideas of what it could be? aything to be real concerned about? the motor only has about 5000 miles on it and hasnt seen more than 7lbs of boost. or over 5000 rpms

 

anyone?
