Wow!!! That's pretty impressive! THat just goes to show us all how much there is to tuning, although, in my opinion, you might have been running pretty lean. No knock to speak of? Congrats are in order! You might want to think about pinning your crank, too.

wideband is on order. crank pin kit will be on order on monday.

fuel pump is in and working good. no noises and fuel pressure is a little better than before. so far so good.


*EDIT - did some logging on my way into work today. Fuel pressure is much better. under WOT, seeing 61-63psi fuel pressure.
also noticed my inj duty cycle is a little lower as well under WOT. happy easter everyone.

another UPDATE:

Magnavolt is on order from blown 364. Got the wideband in last night. We'll see what happens next. It goes to Senge High Performance for Yank converter install tomorrow.

Fuel pressure seems to be OK still, but i'm still not satisfied. I want more piece of mind, so Magnavolt is next.
