The stock ecu will run your car just fine up to about 14psi! With a good.fuel pump and fuel pressure set to stock, you will run about 10.5 or so afr while wot. No need for a tune and will be super reliable.

Sorry to bring this thread up but stock sr's are tuned till they max out injectors, then as more boost you add it starts leaning out, my atock sr20det does about 10.2 afr at wot at 7psi no tunning needed unless you want to lean out the afr to make more power or when upgrading injectors/maf when your tuned for a injector setup your tuned till they max (correct me on this if im wrong lol)
