A/F ratio's......?
ok, i turned up my boost to 14psi, ppl say its save to run at that. on the stock fuel system. i have an apexi turbo timer that has an A/F ratio on it, but it only goes into the ecu for the o2 sensor, so ik its not accurate but, its telling me when im under alot of boost that my A/F is like 10.1 or so. is this really bad? i do have an aftermarket boost gauge so ik its only 14psi. ne info would be great, sorry if this is in the faq i looked and didnt see anything in there.

Re: A/F ratio's......?
I bet your turbo timer is set up to use a wideband O2. Tapping off your ECU gives you narrowband, which is completely useless in tuning heavy acceleration.
