I just upgraded everything to the stage 4 TMI from Turbo XS and everything went in fine! I had a Greddy Profec-B boost controller in there originally and at first we went with that instead of the turbo xs controller and WE GOT BOOST but we also got misfiring due to what we think is the UTEC making fuel do it's own thing and the Greddy trying to mess with the fuel too! We then hooked up the turbo xs controller and get a constint 10 lbs (if that) no matter what we do, then we went without a controller and still get 10 lbs. The controller from Turbo xs is on correctly but as I said there is no boost so I need to know what little peice of crap is keeping me from my 12 second car, is it something that could be caped off or cut when the Greddy was hooked up and is still effecting the other controller because It did work until we un-hooked the Greddy (with the exception of what we think is too much fuel). Or is there more controlling the boost then the connections between Waste guage, Silniod, turbo, controller, and the attachment to the airfilter that we are not seeing or do not know about, that also controls boost. PLEASE ANY IDEA"S and ALL IDEA"S WOULD HELP A LOT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

are you saying that your turbo has stopped spooling. Because I find that kind of hard to believe. Or are you saying that you can't get more than 10 lbs. of boost.

 

No more then 10 according to the stock boost guage. The only boost we got was when the greddy was hooked up but around 16 psi the Check Engine light would start flashing and the car would chug (if thats even a word)

So let me make sure I am getting this right. With the Greddy hooked up you got up to 16 psi and your boost meter showed it. Then with the other TurboXS module you can't get more than 10 psi. Are you sure your boost meter didn't go bad.

 

yes

 

Good news the turbo xs controller was bad and didn't come with the brass restrictor SO... Three extra restrictors and new boost controller later, all I got to do is mess with the timing and fuel map! Anyone know what setting the two swithes under the UTEC are suppose to be at when at a high elevation? I am getting some hunching and either turbo or fuel cut off when the pedal is at the floor?

Other then that things are back to good so thanks for all your help guys and hopefully you can help me figure out the fuel crap next.
