Okay I got a 1985 buick ttype and its converted over to 86/87 intercooled !! Brought it that way! Now i did 3in single exhaust, and now i just completed fuel system up to the rails. NOW My big question is I'm about to order my chip and 60lb fuel injectors from turbotweaks. So it saids 86/87 ecu than 84/85 with 86/87 ecu! How do I tell the 2 apart? Is there a difference even tho the car is intercooled With ecu? I'm a noob on buicks what did I need to look for ? Thanks scott
