I little update. I'm now running a stock 1.8T AWP ECU @ 13psi. I was running out of injector at well over 95% duty @ 5500 RPM on gas, not even on E85 which was above 105% @ 5500 RPM.
First problem I've run into though once I up'ed the boost from 6-7 psi to 13 psi was a misfire on #1 cyl under any moderate load. I swapped coils and found it to be the coil pack. I stole the coil from my MK2 and misfire was fixed.
Plug looked fine to me.
So, I've put in 630cc injectors with a VR MAF housing to handle E85 and gas.
cool down to install the injectors
Thanks to Clay@CTS for getting the injectors to me in 3 days
4bar FPR and stock 1.8T 317cc injectors out
stock 1.8T 317cc injectors with USRT extentions (anti-spacers)
317cc vs 630cc
swapping stock 1.8T MAF housing (2.375" ID / 2.75" OD) with VR MAF (2.75" ID / 3.00" OD)
Cleared trims and adjusted fuel to -25% (as far as I could) via unisettings. I also pulled ~6* timing out to account for the lower calculated load due to the bigger MAF. After running my trims are +0.9* and -7*
I haven't calucated inj. duty yet but looking at the vag-scope while driving it's way down below 80% (again on gas). Once I finish this tank of gas, I'll go back on E85. Only reason I went back to gas was I couldn't wait to turn up the boost from 6psi which I couldn't with E85 @ 105%+ duty.
