ECM Tuning ?

[rxmartin]

Hey everyone, I am new to the board and I need some help with my 87 Grand National. Here is the problem I purchase this car with a cam already installed. The guy who had the cam put in forgot the size of it. The car passed tail pipe test with no problems and still has a good idle. So I am assuming the cam is close to stock applications. I want to install a 3' downpipe with a new high flow cat, 2.5 catback,37lb injectors delphi/lucas injectors, cold air intake, RX fuel pump w/hotwire, adj. fuel reg.. I will be running about 18 psi on 94 octane. I was wondering if anyone could help with a ecm chip for this and still use stock emissions (EGR, closed loop idle...).

Thanks
Kevin

Ugh, if I may, I'd suggest first, doing at least some research about what to do before doing anything.

Before modifing it, get familiar with what stock is. Get a laptop, and a scanner and see what normal is. There's a procedure called Spring Cleaning, find that and do it berore anything else.

Then do all the catch up maintance.

Then think about mods..

I know what stock levels are I just need to know if I need a custom chip for what I am doing or can just use a red armstrong chip 93.
