well i needed to get this done and finally got to it. i knew my rb was slow. and to beat tough competition like shane i have to "power up". iam running this

-stock rb ecu
-whal 255 lph fuel pump
-fmic with 2.5 piping
-jwt intake cone
-j30 diff
-nismo fpr
-3"exhaust with no cat

and injectors are stock. i knew i was running pig rich even with the rb20 fuel pump. but had no idea it was this bad. gas mileage on the highway is 300 a tank. but in the city it's literally 200 a tank. thought it was the diff. but nope.

ryan of mkc informed me it is solely because iam lacking a tune. and i need to be leaned out a bit. he also said i had an extra 50 hp easy(right now). if i had a tune. so thats good news. also the sr20det guys when they swap in thier motors face the same thing of lacking a tune. i got the graphs and iam going to send them to my ecu guy so he can come up with something.

i wanted to put this on hold as i was going for mt 1jz swap but this demands more attention for the moment(trying to do both).
