Hey there, so I'm just curious as to if I can tune the stock OBD1 ecu or if it would be better to use an aftermarket ECU, I currently only have, DC Sports 4-2-1 Headers, An AEM intake, and a greddy catback exhaust, and plan to install a skunk2 intake manifold, I searched around and have seen that eventually i migjt need to mess with the ecu side of things but still want to be able to pass smog,any recommendations or suggestions? Sorry if I typed a little weird I'm new when it comes to ECU stuff. Thanks in advance!
