ok, within the week i should be able to start my 87 monte SS, i just have to put in the distributor, plugs, plug wires and fuel tank. Then hook up 4-5 wires and turn the key. Its a 350 tpi SD rebuilt engine and t5 tranny. I have a modified computer already(basically stock program), i bought a modified stand-alone Speed density harness, and the guy programmed the ecm for a 350 , t5, and removed Vats. However im thinking I may need more of a custom program. I installed full length heades and a K&N filter right on the throttle body, and i heard that SD is not as forgiving as MAF and needs re-buring for most mods. I also removed the air pump and air select/diverter vales. instead, i installed dual 3" regular cats(no AIR tubes). I'm still running the EGR valve and the charcoal canister(purge).

SO... i need to know if i need to have my comp reprogrammed for the headers, K&N, and emissions changes, and if so, IS there anyone who could do it for me? i'll pay, thats not a problem. let me know Thanks in advance. -Paul

You've done nothing signifigant to require a change in programming...that said, you could probably squeeze some more out of it with tuning in the chip...again, though with just exhaust, the ECM will compensate for fuel mixture.

 

ok, i just wanted to make sure the headers and k&n wouldnt need any changes. Its not going to be my car, once its up and running, it being "sold" to my gf, the whole reason i built it. So i'm not looking for every little hp, its just going to be her daily driver. I want to get it done and out of my garage so i can start on my cars once again.
