Disclaimer: I’m taking it to the shop next week but in the mean time just curious if anybody’s has had same issue

Titan eos port kit
Garrett gtx turbo

Basically the car has been running great up until when I last drove it, last weekend. Drove it last night and today and it won’t go over 3 psi. I did turn it off last night and started it back up, boosted like normal on my short drive back home and then today i went out again and she’s back into limp after 5 min of driving. Ethanol content gauge going from 1-60 (was at 75 when running well). Sound like an issue with the reflex? Maybe fuel pump dying?
No check engine light

Your going to have do a datalog of your car while it’s doing it and go over everything or send the datalog to your tuner.

It could be boost cut, lean protection, limp mode, or anything…..

I had a similar issue, except stock turbo, visconti flex fuel kit, catless DP, tuned on Ecutek - Flex Fuel.

I had a bad tank of ethanol.. depending on how much ethanol you have left.. drive calmly till the tank is near empty and refuel and if possible get some of this conditioner.

After I added conditioner and drove a little for it to mix, i started boosting a lil more but not full power until I drained and refilled.

I would log it and have your tuner review. Also pull your codes using your ECUTEK adapter, ive seen codes present that dont trigger a CEL

was wondering about that too. Tanks almost empty, going to do some logs in a bit and try to run most of the fuel out.

Hey guys, got the issue resolved. Had a bad connection with my boost controller and something in the port injection. They had to re wire a couple things and it’s as good as new again
