yup, remove the check valves, install a straight section of hose from the manifold to the map sensor.

just go out and look at your car, jeff, the map sensor is attached to the firewall, on the passanger side.
the stock GT map sensor has a blue sticker on it IIRC. wink.gif

i would recomend the aem uego wideband bought mine off ebay to save a couple bucks but its great and extremely accurate

off topic, for the air/fuel wideband; do u have to 2 install 2 sensors? 1 in the intake, and 1 in the dp ?

ok got the sensor today ill be putting it in tomorrow but does anyone know what i need to change on the safc2 to get it to run smooth (how much fuel to add or subtract)

ok added nine to the fuel at low throttle does that sound about right........and my wideband is saying lean but when i keep addn more fuel i can start to smell it can sum1 help?

why are you adding fuel @ lo-throttle points?
you SHOULD be lean under lo-throttle, off boost conditions.
as your approaching boost, and into boost, you should be 11.5:1
everywhere off boost you wanna be between 14-15:1

if your "wideband" dont give you an exact A/F ratio #, then its NOT a wideband.
those "lightshow" regular o2 sensors are pretty much usless for tuning.

your running supra injectors, right?
315cc, not quite as big as they should be to jive 100% with the 2 bar map is my guess.
see, with the 2 bar map, its basicly a balancing act of getting in big enough injectors to have pleanty of fuel up top, while still being able to tune out the richness you normally get in the low end.
are you using the stock FPR ect?
i never had the wideband sensor in when i had the 315cc injectors in my car, so i cant tell ya how lean i was at idle, but at the dyno i used one, and with how lean i was everywhere else, including in boost ( i was as lean as 17:1 in boost before tuning)

well i was readn up and it seems those arent good injectors so i took em out and put the stock ones in (which do i need) and im using a 12:1 vortech fmu stock fpr stock injectors and apexi safc 2

well, no wonder why your so lean. you NEED to be using larger injectors with the 2 bar map.
the FMU is gonna help you blow your motor, and thats all. take it out.
get at the minimum 315cc supra injectors (no, not the 440cc LOW impedance ones celiracer suggested you had.) on an ST, i would try the 315s first (i think i may have a set of 4 of these if you really need them)
and try to have a set of 360s, or somthing a little larger just in case.
the 315cc injectors will provide enough fuel for ~190whp.
that should be more than enough to get you up and running @ low- medium (5-8psi or so) boost.

i have the 315's too i chose to put the others in i guess i should change that lol but i had a friend put them in and idk how to put them in cause the bolts are blocked by the intake manifold which idk how to get off help would be great with this and whats this about the fmu i should just take it off and run w/o one the stock fpr and the bigger injectors with the safc2 and i should be fine?? and just to make sure the 315's are the lime green tops correct?
