I have been reading and researching but I wanted to get some opinions from people who have tried different setups. My current setup consists of a 14b turbo, 12:1 fmu, stock injectors, 255 walbro and a fmic. I am currently running extremely rich and wanted some advice on what to upgrade next. I like the 14b turbo's quick spool and ability to hit 300hp with the right supporting mods so I want to keep it. I will probably build the motor to handle more boost in the future but wanted something that I could tune with now and be able to use when I build the motor later. Any suggestions?

MSnS seems the obvious choice there

The only things that I know of that you can use to tune while in boost would be Hahns Portfueler, MSnS, Emanage, AEM. The cheapest for the most would be the MSnS, Portfueler would be the easiest to install and set up, someone just got Emanage Blue working for the 2gnt-you would have to research that, and AEM-most $.

Thanks for the response guys. I need to do more research on how portfueler and MSnS exactly work but I wanted to know what other supporting mods are recommended if I decide to go with MSnS which seems to be the more popular choice? Like what type of injectors would I need to upgrade to, etc....

Do you have a wideband?

Nope. I'm still running the cheap blinky air/fuel gauge but I definitely know i'm running rich. My exhaust tip and back bumper are covered in black burnt fuel and the smell of burnt gas is really strong when i'm idle. The gauge also goes beyond rich when I step on the gas. The wierd thing is that when I first installed my turbo kit this past summer the car ran great for the first month or two until I blew one of my couplers off while driving on the highway. After I tightened everything securely the car started running rich. I even reset the ecu a couple of times, thinking that things got screwed up on the drive home after I blew the coupler but it did not help. Been running rich ever since.

Well, since you're running rich at idle, I don't think your problem is related to boost. Check your O2 sensor...it may be bad.

First off your FMU is going to put your stock injectors at a higher pressure than they really need to be under boost. The correct ratio is less than 8 to 1. You could get a 8 to 1 adjustable FMU to correct it. I also have this issue currently and I am in need of a Tune and a Wideband really bad
