I removed the TCU when I installed the shifting cables,but for some stupid reason,I put it back in.I only remembered when you asked if it was removed.That was a customers car.Thanks guys.Will be posting shortly on my build.It's a 95 GS with a 420A,the engine was built by Howell Automotive as a Short Block and then assembled in house. It has JE 8:6:1 comp pistons and Eagle rods, the block is bored out to 20 over.It has a Hahn Race craft Port fueler system,it has 550cc s on top of the stock 270cc injectors.The head was fully ported,posished with Crower stage 2 cams,didn't figure out what springs,and valves to use yet,but will have it together soon.
