Thank you. I haven't noticed any negative effects yet. I'll keep an eye open for them.

I have recently learned a few things on controlling Idle on my 03 C5 (Fast92/LS290 TB, big cam with 14 degrees overlap):

Long Story shortened... I hope;)

I have a 2003 C5 Corvette M6 that I track. I just had a new top end rebuilt by my engine builder/friend. The parts we used were:
