we have a 95 t56 camaro with a high compression LT1 . its a 358ci running 14:1 compression.. the car pops at certain rpms sometimes high rpms or mid rpms when under a load.. this motor is built to redline at 7500rpm. we had the computer sent of to be redone and we are running stock injectors and the map sensor is reading low. ?

we dyno'ed the car with it runnin like this and it only pulled 410hp took it to the track and it just wanted to pop and breakup around 5000-5500 rpm...with a 13.7 @105 mph... ug ..

really need help and cant think of any other symptoms to give you guys... its late ... ?

all help is appreciated ... this car is very impressive and we are looking to pull some times like tanner is .. but we are stuck at this point...

 

Thats a LOT of compression I'd hope to God you're using very high octane gasoline. 93 or 97 octane. Could be the injectors too though...
