Ported LS6 intake
I wanted something different so I went with the Lingenfelter intake.
You need to check the duty cycle on your injectors as they run now. Then you'll know if its time to upgrade. The addition of the intake only without a cam will not make you need injectors.

I got a FAST 78 for sale in the classifieds section, and acutally since your sig says you have an 85MM TB, i remember a guy porting the opening of the fast 78 to 85MM (since the rest of the fast 78 is exactly the same as the 90)

I have a ported LS6. Gained me a few HP on the dyno. I was up about 5 RWHP after porting the intake and installing an UDP. The gains would have been 8 - 10 RWHP higher, but switching from stock wheels and 245 tires to TT2's and 315s limited my gains. Also, no need for larger injectors, it wont skew your a/f much at all, plus closed loop will adjust for it anyway.

well on the way i have a G5X1 cam and a set of Dart Pro 1 Ls1 heads that will be ported and polished and if it is necessary i may get the lingenfelter intake to match the heads to get full use out of it and then new injectors would that be a good combo????
