INTENSE did this. Numbers didn't look too good. Don't recall them off the top of my head.

stock i was at 15.2@92mph , and the conditions of the track wasnt perfect.
im sure it can play between 15.0 - 15.2 for a stock '00+ SSEi .

FACT:
GXP'* are NOT quicker than an SSEi at the track.

They are PROBABLY slightly slower. Close, but not quicker or equal. They weren't designed for that.

Yea,I guess the Pontiac brochures 1/4 mile times were not real either.Must have been estimated or simulated.

Brochure numbers just don't match stock car reality at the dragstrip. Brochure numbers on the Northstars power don't match dyno reality at INTENSE, either.

Not sure what'* going on there.

I think it was said somewhere that they did that as they did not want a Pontiac to have as much or more power than the Caddy 4.6, so its slightly detuned... Not fair is it... :?
