I was looking through some of the tuning threads for the OBD-I 2.2L's and was surprised to even see there were options.

In my excitement, I forgot to think that I've got the TH125 and was wondering if that is of any concern?

I've got a ported head, 1.6 full roller rockers, generic SS header but the car is still being worked on, so the rest of the exhaust is not finalized. I do plan on reworking the fuel system (to include an injector swap) and a mild cam in the future too. SO getting it properly tuned is gonna be a must.

I was not thinking when I posted this LOL Blame the chronic...

The TH125C isn't something to worry about, just in case anyone else has any questions like I did. It's not computer controlled like the new-ish OD transmissions are.

Sometimes I ask questions before I even think about it LOL

I still haven't checked to see what kind of ECU I have, so I can begin the process of collecting tuning parts.

I've been very tempted lately though, to swap to TBI for ease of fueling, but I've got to find a TBI engine first. I've got 2 complete 94-97 setups but no TBI.
