just bought B 303cam, gt40x heads, timing chain, upper/lower trick flow intake manifold street burner for my 1990 coupe mustang fuel injected. you guys think i will need to change to a upgraded computer or should be good with the stock one? in addition i also have xpipe with cats, bbk shorty headers, 70mm bbk throttle body and bbk cooler intake etc... if the same computer can with stand it then i should be good not wasting more $$thanks.

Your stock ECM will be fine.

Edit: I'll elaborate, with my mods, most are in my sig, the stock computer does a great job with AFR's at all throttle settings, and everyday driveability is very good.

My car ran mid 10s on a 200 shot of nitrous on the stock PCM. Your good.
