Shift issues after intake swap
Hey guys,
Long time user, first time poster.
I just recently swapped out my stock ls1 intake for a ls6+85mm TB. All went well and the car drive fine for the first day. I am now noticing that the trans shifts early at anything but WOT. At WOT it shifts normally but I have a huge power loss right after the shift. I have also noticed that at part throttle it will shift very early and the shifts are tighter than normal (i.e. chirps tires when shifting at 3-4k). I have checked all plugs and vacuum lines and all seems normal. I have yet to check TCC/TPS readings. Thanks for any help in advance.
Vehicle is a 98 Camaro SS with the following upgrades:
CAI
LS6 intake/85MM TB
LT's
Full exhaust w/o cats
AIR/EGR delete

I will be putting a cam in next week so I planned on doing the tune then.
Not sure if this helps but from a stop until first shift the car performs beautifully. There was a noticeable gain in hp after the swap. Its when 2nd gear hits that power is lost and it kinds bogs down.

Finally got around to replacing the TPS. The shifting is fixed now - horray! Unfortunately, now I have an idle of around 1200 in park. I unplugged the sensor and turned the key on for 30s, turned off the key and plugged the TPS back in. Same idle in park. Any ideas?

Back again with the same problems as before. Had it tuned by Frost and it seems to be running excellent, minus the bogging down immediately after shifting into 2nd. This problem initially happened after changing to an LS6 intake and aftermarket TB. I have tried a new TPS, but the problem was soon to return after doing so. Any suggestions? I would really like to take it to the strip this weekend and see what type of numbers I can pull.
