run through the calcs yourself and see what you come up with :thumbsup.

I'm running #30 injectors at about 20psi at idel and have the 2.72 disk in my sfmu....which I believe around a 5:1 ratio. just to give you an idea.

I'm also running the Cartech currently w/ 30# injectors. I've got my idle fp around 20-25psi and @ 7psi my fp is around 65-70psi. MY EGT's are right on the money and it pulls nicely.

Why such large injectors for so little boost? I'd be scared running 20psi idle pressures.

I did have it up to like 10-12, but I'm still running stock exhaust, so I turned it back down to like 7 for the time being until I upgrade my exhaust to a 3" cat-back setup. I'm also in the middle of building my 8-inejctor setup so I'm just keeping it somewhat sane for now.

Im in the same boat man. 9psi and I'm getting 100+ pressure which is killing my top end. :(. If I don't floor it all the way, say 90 % throttle it pulls like a mother fucker! But ass soon as I hit the gas all the way the power dies off from like 4500 and up. SFMU on the way!
