I’m just starting to tune my recently installed TSI turbo kit and can’t seem to get my AFR to 12 at full throttle. I have the Attitude industries fuel controller and 3rd injector setup, I can only get it to 12.6 AFR with all fuel settings maxed out. I’m running around 7 psi. I am going to reach out to Attitude in the am and see what they suggest, but any help would be great. I’m thinking it’s either a weak or plugged fuel pump or the controller needs to be remapped. Any suggestions?

The Attitude controller sure looks like a re-branded Dobeck controller. If it is, you can send it to them and they can remap it to allow more fuel. I take it you've already maxed out the different zones (green, yellow, red)? I had a similar issue when I went to a big bore and ultimately chucked the dobeck and got a Power Commander and Autotune. It has so much more control and I wouldn't trade it.

Yes I have maxed out the full throttle zones. Attitude industries is trying to work through it with me, but we have checked fuel pressure, boost sensor, injector and everything checks out. They swear the map is correct on the controller, but the next step is remapping controller I guess. Am I missing something? The 3rd injector is also a 700c so I should be able to flood it right out.
