If i got my car tuned because it has 10.5 to 1 compression and a lt4 hotcam and longtubes with no air. how much better would it run i honestly want to know before i go out and buy the stuff to do it.

 

If you are asking about PROM tuning, there is a lot of room for improvement with even a stock engine. Since you have no air injection, it would be appropriate to turn that off in the program. With the cam change, the WOT (open loop) fuel trims are really going to need a change, as well as the spark advance tables, since the dynamic compression at a given RPM is likely considerably different from stock.

 

thansk i will be getting it tuned pretty soon due to the factthat im tired of like 7 to 8 miles a gallon

 

lol woo woo i just got 12 mpg this weekend with an untuned MAF 305 with a zz4 cam, 1.6 rockers, ported 601 heads, and the completely wrong spark plugs. lol but it sure does move at WOT.

 

hell yea that would make me feel good about it but im gonna do some **** next weekend to it plugs wires and new ignition coil and also fix my airbox theres a huge hole in it and all the clips are gone out of it so i needs new ones
