Congratulations! You made it.

Haha thanks. Almost set it on fire countless times.

I just want to conclude this thread...

There was probably other minor considerations at play here but the problem was the injectors.

Even tho I had them cleaned etc, they must not have been able to deliver the fuel required for the the stage 2 JBS tune with the 4BAR FPR.

I must admit the guy who cleaned them was a tossbag and did not not supply me with any flow rates before and after but 'assured' me they were in good condition.

However, the 4BAR FPR over drives the stock injectors by a certain percentage 5-15%.

I replaced with a brand new set of Bosch injectors and the car is very quick again.

Does the solenoid get lazy over time? I noticed he offered a different style of pintle cap on the injectors with a more prominent tip. No idea if that has any affect.

So I would suggest that if you do have your injectors cleaned pay particular attention to the flow rates. If they are slightly uneven, or if one has a minor leak, bin them and get a new set. You won't get any codes from a AGU MK4 in this regard.
