Stillen G3 Intake + CBE = too lean?

ThunderZ34 · 10-01-2010, 12:21 PM

Can't seem to find this info, maybe I'm not so good at searching...

I know for Twin Turbo Z32s it is 11.5 and 18 degrees to be on the safe side with 93 octane.

What is the proper target Air Fuel Ratio and Timing for the Z34 at WOT on 93 octane?

Stillen has done a GREAT job of keeping the intake calibration in check with the G3 intakes and their exhaust components compliment them perfectly....

Ok...just to make sure I'm reading this right...If you have the Stillen G3's, and HFC and CBE combo you're good...not running too lean and won't need a tune...but if you add a header or anything else more on top of this three combos you will need a tune right? Did I read that right?

I have Stillen's Gen 3 Intake, Invidia Cat Back & Invidia test Pipes installed.

I got my car dyno tuned last week at Ivey and the A/F stayed exactly the same (so says the dyno print out)

As for running too lean, i'm assuming you have nothing to worry about.

I thought I would see some type of change in the ratio but I guess the ECU auto adjusted??? Or no change was needed.

Maybe someone with more tech knowledge can chime in here.

As we've said.. with the addition of headers to your setup there is some concern for the ECU's ability to adapt and could cause a lean condition.. but not with just the addition of intakes.

Enjoy!
