Granted there's a few lines in the above with a few 2x count knock entries per line for 2 lines but, at this point I'm not sure if this is a cascading effect from the off boost knock. But that's one of the roughest knock runs that I could log, the rest might have 00001 or 2 knock counts barely but otherwise minimal knock when under boost. Hmmm. >_>

In case your wondering about the boost, the aps kit (tt) wasn't making more than 4psi with the fully stock exhuast so we put an mbc on it to coax a max of about 6.7psi out of it on the UTEC MAP, any more and it didnt make any more power just knock so we dialed back. 350/370 was the power/tq, and for me that's more than enough provided I can clear up this damn knock. (I didnt tune it, the guy that did tuned my previous 350z to 500whp/tq on a utec version 2.3, so I'm not second guessing his ability by any means).

When I first got the car back I also dont remember it hesitating under boost or anything, but damn being in the shift_probs club really reminds me how much I didn't miss it haha.

this point I'm not sure if this is a cascading effect from the off boost knock. But that's one of the roughest knock runs that I could log, the rest might have 00001 or 2 knock counts barely but otherwise minimal knock when under boost. Hmmm. >_> In case your wondering about the boost, the aps kit (tt) wasn't making more than 4psi with the fully stock exhuast so we put an mbc on it to coax a max of about 6.7psi out of it on the UTEC MAP, any more and it didnt make any more power just knock so we dialed back. 350/370 was the power/tq, and for me that's more than enough provided I can clear up this damn knock. (I didnt tune it, the guy that did tuned my previous 350z to 500whp/tq on a utec version 2.3, so I'm not second guessing his ability by any means). When I first got the car back I also dont remember it hesitating under boost or anything, but damn being in the shift_probs club really reminds me how much I didn't miss it haha. __________________ 03 DB 350z Last edited by Juztin; 06-29-2008 at 11:48 AM.
