Re:when i hit boost
 

first thing the air fuel gauge is not accurate and then get a wide band O2 sensor and then the injectors, the LS injectors will do but they will cut out when at higher boost, the pulse width modulated signal from the ECU is somewhat interupted there lacking the fuel that the turbo needs.
YOU NEED MORE FUEL

Its not a question of how "new" the A/F guage is... Mine was brand new too...

Its just not accurate..

Re:when i hit boost
 

the widband o2 sensors are like 300 bucks

Re:when i hit boost
 

I know.... Sucks, but its the only way.... Dyno shops have a wideband that goes up your tail pipe... A place in Orlando by me charges $75 for an hours with the Dyno and using there wideband.

Or you could spend $300...

Sucks I know, but just b/c widebands are expensive doesn't mean your A/F gauge is right ( mine is WAY oFF ).

Re:when i hit boost
 

their is a shop near me that charges 100 for a hour of dyno tunning. i just want to get the car out of the rich zone. I was looking at the s-afc controllers the other night and how do they work. or actually the functions fo they wide the injector pulses

nnnnarrghhhhhkkk!!

a/f gauges are a waste of time unless you have the right o2 sensor for it.

i didn't even bother getting one. the only gauge i might get to tell my mixture would be an EGT gauge, but i don't know where i'd put it.. ohwell.
