ok, so ive got a twin throttle body manifold, but im worried about what will happen to my transmission characteristics if i bolt it up and dont re-tune the memcal.
i am gettin a dyno tune soon, so it wouldnt be left untuned for too long...but ive heard some stories about oversized t/b or twin t/b causing issues with the 4L60E. im imagining the shift points would be all out of wack because the TPS would be giving a reading, but the amount of air let in would be alot more than its telling the pcm.
im just guessing here, but if anyone knows from experience with this sort of thing and could help me out id appreciate it. i just want to know whether its going to be ok (as in, not a pig to drive) for me to bolt up the twin t/b manifold now and drive it around untill i get it all dyno tuned up in a couple of weeks or so.
