View Full Version : Running super rich on RB25 S2

08-27-2012, 12:24 PM
So, I got my wideband installed and went for a drive. My car is running at 10 PSI stock turbo and my AFR readings are around 7.XX - 8.XX at WOT. A full tank of gas on my S13 only last for 3-4 day's. And car bog's and feel sluggish.

What's installed on the car:

Freddy intake manifold
Walbro 255
Q45 TB
AEM TRU Boost controller
Innovate MTX-l Wideband
Stock MAF
NGK Iridiums BKR7E
Stock injectors
Coolant Temp Sensor replaced recently
Z32 Fuel filter
Stock Coilpack
Unknown brand FPR

Any suggestions?

sounds like you need fuel management like nistune or apexi power fc. Im in the same boat.

Have you decided what management you going with? Thinking about getting a Power FC couple paychecks from now. If I could source a Z32 ECU I might go with Nistune.

I hope that fixes my issue and doesn't just cover up another problem.

Thanks for the suggestions. Just let me know if there are other things I can check.

Thanks again!
