    I will say if you have a ECU from 96-2000 you will be pissing in the wind if you plan on 6800-7k rpm shifts. Im currently at 600hp in my 2 valve with a 2000 ECU controlling my built 4R75W. The problem, shifts are being commanded early around 6200 to shift between 6500-6800 if there is wheel spin. However, the friggin ECU processor overloads and resets the ECU above 6800-7k rpms. My gauges do a full sweep when I try to do some WOT pulls on the street. Not exactly the thing you want to see.

    I have a 2004 ECU but the pin outs are different.

    Yes u can use the bombinator ecu so u can control every shift point. ATF is here local to me and they did the trans for my buddy's turbo 07 gt that was going 9.60's making 850+hp.
