Thread: Low boost, any ideas?

So still searching that issue but decided i'm gonna wait until i change intake gaskets since they are leaking. I also dont get a constant 3-4 degrees of kr. Its erratic but out of ten pulls 7 were 1-2 degrees and the others were 2-3. I still get a very occasional 4 and spike 6 however on one. My o2 b1 is lower also which is around 890-930 depending on the pull. Still running negative fuel trims however and for some reason 100% injector duty on shifts however it is better than previous intake setup where it was 106% on shifts. I'm not sure if that injector duty cycle is normal on a stock car with just an intake?

U lost me. What do u mean stretch tube?
