Yeah not a clue, I definitely run fine though, I know the fuel pressure is plenty good for a 75 shot, i run wet shot, and the gmpp manual for this car says nothing about upgrading fuel until much later.

Fuel pressure specification is 50-60 psi (345-414 kPa) Having measured it numerous times, I have found it to be closer to the 60 psi, even under load. I would think using 50psi would be the safest for your calculations though.

Thanks guys !!!

Tell me you're not doing a 3.0" pulley + nitrous?

Not saying it's impossible, but seriously, watch yourself man! You're in uncharted territory here... and from the looks of your dyno results, you're already leaning out a bit at the top end!

Good luck tho!

Maybe I'll install the nitrous kit next sprimg only, but since it's a wet kit, there should be no problem, since there will be nitrous AND extra fuel injected.
