now i can see i'm running lean. take a look at my mods, do you think adding a upgraded (higher flow) fuel pump will get me into a safer mixture range? all the mods from the reman engine on were done at the same time. i was at 11lb boost now 15lb. the comp was reprogrammed by m2 when the down pipe and air box was done.

Is this what you installed? If so, its crap (sorry dude but you got ripped the F*ck off )!!! You would have been much better off buying another 2 refills of gas or perhaps a stuffed animal for your car!

BTW: I'm assuming that you went to M2 and they strapped your car on a dyno and they reprogramed your ecu while tuning your FD on a dyno and quality/professional wideband/lambda meter to a 11-11.5:1 A/F ratio right? If not, I would really suggest you not to boost to 15 psi and stick with the 11psi.

In anycase, just upgrading your fuel pump will not do much, you need to upgrade your injectors as well as get a ecu that can be tuned to your own car (stand alone via AEM Power ecu or PowerFC or Motec or what ever other brand which is currently availble).

 

yes it is that one. not everyone has unlimited supplies of $$. maybe in the future i can get a full management stand alone.
