hey im looking into aftermarket ECUs or performance ECUs for my ss
anyone know much about em and what ones to look into so please help
What kind of work are you doing? The stock Delco ECU's are quite tune-able for many applications.
If you have an auto this is going to require a lot more than a good tune.
For starters, do you have a stage 2 shift kit and corvette servo? If not, thats your starting point.
I could make my relatively stock manual SS chirp 3rd gear.
All i can see it requiring would be; 80 - 90 km/h, a boot full of throttle, 5.5k RPM clutch dump and no mechanical sympathy.
