Cam install, tuning question (HPTuners)
I’m installing a FMS 232/234 598/598 112 cam in my 2001 Trans AM. I upgraded the valve train to dual-springs, hardened pushrods, titanium retainers, etc. Few questions that I have:
1. After I have installed the cam, do I drill the TB to maintain an idle or do I tune the PCM to try and keep it going?
2. Do I drive the car around to try and get it to learn some new settings, or are there things that I can change via HP Tuners right away
Those are my two basic questions. The cam should be here next week, so I’m doing a lot of reading on Tuning etc. Does anyone have any advice or things I should change via HP Tuners (or even a pre-made .bin
that would help. Any help/suggestions appreciated I’m installing a FMS 232/234 598/598 112 cam in my 2001 Trans AM. I upgraded the valve train to dual-springs, hardened pushrods, titanium retainers, etc. Few questions that I have:

I just fired off my modified (cam/heads) LS1 and was having trouble with NO idle. Hooked a Tech II on and could not even get control via the IAC.
I opene the t/b a tad with the set screw. WOW! It let in more air and I am now able to idle enough to try to start driving it for a relearn.
I was told to drill a hole next if the opening adjustment didnt' work.
