I have a simple question. Is there any advantage of replacing my current stock 20 year old ECM MAS flow setup with a speed density system such as a FAST XFI system. How is the tuning and driveability? What sucks about the FAST system other than price?
My current setup is typical nothing radical;
3" inch THDP
Full 3" dual ATR Pitbull Exhaust
Stock Block, heads, intake and bottom end
Stock Rear end
The future upgrades I'm looking at are 50# injectors and Champion Iron heads(maybe) and a Power Plate.
My goal is to have a nice ride which is strong and dead-nuts reliable and I'm looking to see what can be done with the current Commodore VIC-20 ECU . I don't have any intention of turning this thing into a 10 sec car anything, I just want to increase the reliability.
