thanks

i would say most usefull would be

1.A/F
2.boost
3.fuel pressure
4.oil pressure

I went with boost, fuel pressure, and oil pressure. If i would have had the funds at the time i would have gone with the wideband A/F

^^^ I would agree w/ 1,2,&3 above. I think boost and fuel pressure are the most important. AF is too but, I have less interest in that personally. All are critical to tuning and safety.

P.S.I.cho

if it were me i would leave the A/f on the bottom of the chart and replace it with an exhaust gas temp gauge, at the dyno you can use the dynos exhaust gas analyizer to read a/f ratio but you cant see EGT's, EGT's are a huge part of tuning.

egts?? i always tohough af was important cause my car will be a daily driver so i would wanna make sure its running right everyday i turn it on. what do you guys recommend for mounting solution and guaging for an 05 gt? i wanna have a nice clean look.

thank you

Erm the wideband is the single most important gauge on any FI application. Remember air/fuel ratios change daily due to the changes in the weather, barometric pressure, bad gas, humidity, temperature etc etc. Who ever says a wideband is the least important gauge has no idea wtf they are saying. The most imporant gauge is the wideband, fuel pressure and pyrometer (exhaust gases temperature gauge) The boost is important but only after those 3. The only thing a boost gauge will show u is if there is a leak on the system, if ur are s/c if the belt is slipping and thats about it. Not as important to conserve ur engine as a wideband is.

meh.. fuel pressure isn't all that great. by the time you realize there's a problem, it's already too late.

androdz

Yes but if you are sitting @ traffic and you see your fuel pressure being eratic you know already not to hammer the pedal

wow you guys know everything thank you very much. my biggest concern is exactly what androdz said about your jus at a light and something happens i wanna know cause teh turbo was expensive enough so i cant lay out for a motor build yet. thank you again guys, very much. i gotta figure out mounting solution next.
