If you plan on over 400+ hp look else where.

Here is the thing the more power you make the more fuel you need. If he gets his setup dialed in and starts running 13's those injectors arent gonna be enough. Im at 95% at 6250 rpm and I do run 13's he is gonna need more fuel than me because boosted apps like wot afr in the 12's not like me whos afr is 13's wot. I hope Im not just banging keys here.

yeah i understand that, i was just surprised that those were being pushed that far at his level. Not that he isnt making any power, but if he decides to go up to 10 lbs he will be cutting it very close.
