LS3 MAS Problems
I recently put an LS3 in my 67 Camaro, and have had a lot of trouble tuning it properly. We have purchased EFILive, and are still having trouble with a speed density tune. I've decided to do away with my pretty Street and performance 90 degree elbow, and fabricate my own longer air tube. After calling Street and Performance, it seems like I am one of the few have problems with their air tube (but everyone else seems to think that is my biggest problem--tuners that is).
Has anyone else had similar difficulties?Bobby

Can you post a picture of the air intake setup as well as a picture of the Mass Air Flow sensor? Curious to see how it is setup before I make a judgement. You mention a Speed Density tune which is a tune without a MAF sensor so the inlet would not have effect on the tune other then HP potential.
