My F23T build having issues UPDATED(1/27/2018)
I'll just with all my supporting mods I have and then I get to the nitty gritty.
APR turbo back exhaust, APR FMIC, APR RFD, forge twintake, unitronic DV relocation kit, APR HPFP, S3 injectors, DV+, RS4 prv, Frankturbo f23t, and golf R map sensor.
Back in September I finally got around to getting my F23t installed as well as other supporting mods. I ended up having a guy who specializes in eurodyne tunes to make a custom tune for my car. Got it dyno'd and everything. Literally the very next day after I got it back I had very bad cold starts and rough idle for the first minute after the car was turned on after it had been sitting for awhile. Then a check engine light came on saying I had misfires in all 4 cylinders. The coils and spark plugs were brand new and gapped to spec. After it warmed it drive fine, but the engine light still was on.
Now I finally got it into the shop to see if they can see what the problem is. I've been told many things like the injectors are too big for that turbo by the shop tech and even Doug himself said that was bullshit. He also added that he didn't believe that the golf r map sensor played nice with those tunes and may not even be necessary. It's been almost 4 weeks and still no luck with getting it to pass emissions or getting the rough starts to go away.
Is there any truth to my injectors being to big for the turbo or that eurodyne tunes dont play nice with some of my supporting mods??? Just trying to see if someone has any ideas to what's going on because the guys at the shop can't see to figure it out.

I want to bump this thread because I'm running into a different problem. They got a APR K04 tune to work with my turbo without the s3 injectors and was able to pass emissions. Car starts fine after fixing a boost leak I got, but now I'm running into a different problem. So upon cold start when I start driving it kind of sputters when just on normal acceleration. It boosts fine up to 25PSI for about maybe 5 minute and then all of sudden it wont go past 8PSI. Im also getting shitty gas milage. Boost leaks have been ruled out. MAF sensor??? I cleaned it out. Could still be faulty. New plugs were gapped and installed. Thoughts???
