what ring gap? What ring gap would you guys suggest for 15# of boost coming out of a T6 GT-91? Pump gas motor (might possibly go E85 still haven't decided) Motor is a ERL built 402 Wiseco pistons and callies rotating.

Second ring should have a larger gap. Follow this: http://www.wiseco.com/PDFs/Manuals/RingEndGap.pdf

1st is more important than the 2nd. Not saying the 2nd isn't important. The 1st and 2nd are normally spaced further apart. I'd go with at least .028 and don't zero deck the motor either.
If ERL is doing it I wouldn't worry about trying to figure all this out yourself. Let ERL tell you what they think it should have or Wiseco, or Diamond, Callies etc. etc. whoever your going with on the pistons.
