crazy problems after turbo install
ok i just installed my 3076 kit and i srated it up and my idle afrs were like 11.1 and not steady at all. i also swapped my front 02 sensor from an 05 evo during the install. anyways we take it for a test drive and i hit 15 psi and i hit fuel cut. ok now i brought the car back home and my boost gauge only turns on when i have my lights on.....never done that before. i cant figure out what this problem is besides it being the 02 sensor but i know the 02 is good.....any ideas?

Not sure why you think it's the 02 sensor.
If you put in bigger aftermarket injectors, how did you compensate for them in ECUflash? Did you change latency as well as injector scaling?
Your boost gauge is wired up incorrectly. Stuff doesn't just change. Someone moved the acc wire to it.

Definatly need more info on the setup, but if your guage only turns on or lights up when your lights are on and it never did that before then you blew a fuse somewhere. Get a meter and check every fuse. Post your setup

and i didnt mess with any wiring at all, all id id was unhook my battery for the install and then hooked it back up afterwards. and yes it is wired up correctly....
i took my car up to my work today and ran a diagnostics check on it and it said it weas the front o2 sensor (but i just put in a new uiniversal bosch) which i heard works fine in our car.......
so is there anything else that could make my car throw an 02 code?
might just have to get a new oem 02 sensor

The aftermarket turbo flows a larger volume of air than the stock turbo. You cant just go off of PSI. You will have to retune the car and compensate for the different air flow. I have done 2 different Evos with turbo kits and both had to be totally retuned just to idle correctly. Get the Tactric cable and check your fuel trims and adjust the injectors accordingly.
