i have 93 Gsr Motor with type r cams P28 ECU and Apex Vtec controller. When i hit vtec you can here it kick over but no pull. the oil is right toped up i use 5 w30, i changed the vtec pressure solinoid and still nothing, its really upseting because when i first installed everthing the car would pull like crazy and at the track it ran a 14.5 at 101mph and now i just tested it and its runing 15.6 94mph, so i know somthing wrong so if anybody can help it would be appreciated
Thank you

I assuming that you had tune your car with that vafc and the cams.

 

if you messed wiht alot of the vafc settings w/o knowing much about the tuning it may mess up your performance, my friend played with mine one day w/o knowing and it ended up cuttin off dead after 5,800k
