trying to get an idea of were i stand, and dont think im doin good, right now i have longtubes, ory, moroso cai, tuned pcm, making 271. before the tune i made 275 running ****ty. replaced the opti/plugs/wires and thats when i got the tune and went back and only made 271. the pulls were made with 18 zo6 replicas(dont know if thats makes a difference) i have since put in a new fuel filter, and a lt4 KM. im completly lost as to why my numbers are so low.

 

I wouldnt worry about numbers too much, track numbers usually give you a better idea. The wheels probably cost you some HP (~10-15?) and without the LT4 KM you were probably loosing a good bit more HP (~10-15?)

 

ya, i think im gonna head back with the 16's, just for the hell of it, its tough to get to the track, its 2 hours away, and if something was to break, o boy id be screwed

 

anyone else have any ideas?
