Reprogram the ECU for OBD-I

OK, so I am thinking of getting my engine rebuilt and warmed over (Work the heads, bigger valves, port and polish, cam) and in doing so will likely need to burn a new chip. Problem is, who is my best bet for burning a new chip for these mods?

I gotta be honest here, This is the newest sports car I have ever owned... lol

Re: Reprogram the ECU for OBD-I

You can get the best results by tuning it yourself.
You will need a few things from moates.net
xtreme aldl and cable 1, burn 2 and a g1 adapter.
You will also want to pick up a few eeproms sst27sf512.
