If you add an FD upper intake manifold and TB to a TII motor be prepared for alot of re-tuning. I spent alot of time trying to tune my car while I was driving. :p

Sounds like tons of fun. I am thinking of doing that sometime down the road, maybe. I thought that you already put it on there. Why do you have to re-tune your car?

Yeah, it was running "ok" but after I put the motor back in it ran like crap. I needed to add more fuel below 3500 RPM, as well as advance the timing below 2K. Somebody may have fiddled with my map while the motor was out, maybe even me. https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

It definitely helps with the top end. My boost started to go up after I added it.
