i think the only difference is in the controls for the overdrive auto that was used in the tc. im not positive , but the difference in the factory rated power came from the T fitting on the compressor of the turbo that worked the wastegate.it had a different size opening to regulate the boost to 10 lbs. the timing curve should be the same on the 2 computers.

Thats what I was thinking but had to ask. I am going to be switching to T5 eventually but I need to get the parts from a Merkur stick to do the swap. So if anyone has these parts please email me. I have the T5 I just need clutch pedal and cable and what ever else is needed. By the way... is the Boo switch really needed?

I need Merkur parts.
