no its not. that is the best for fuel efficiency. in fact, 15.0:1 is better for fuel efficiency. even an n/a car runs best around 13.0:1 AFR, not 14.7:1.

Yeah when crusing or idle...... X2 what Bio said on the rest. Run a 14.7 AFR WOT once and make sure you post a video of it. Id love to see the carnage lol

It can be done on E85. I don't have a vid but I might have a scan. Lol

There aren't really any cheap kits, I'd go for something around 200 and it depends on your mounting location, aem has a guage, others have something u can mount on the steering column. There is a nice new innovative wideband out...

i did it when i disabled my PE mode while i was doin my maf tune... still didn see any untill it blipped to 1* at 5k rpms

I know i said this but the FAST wideband i think is great and can be had at an affordable price (to my door for 150 bux)... sits right next to my aeroforce gauge on top of my horn!!

aeroforce and wideband are the only gauges one should ever buy IMHO...

Ive not went into PE a few times aswell for some unknown reason. I seen upwards of 12 degrees of KR lol
