Not using it anymore..
Turns out the stock unit flowed better <scratching head>.. Anyway, hit me up with an email so I have the address to sent it to..

I fixed my situation...installed the J valve which only lets me got to 21-22 psi...
but it goes there earlier and stays there longer than the stock or H.
I think Steve was right that I may have overboost. I did a check for leaks, check the IAT, and MAF. Looks all good.

Old thread but I've seen a few people with this problem recently on our now ageing TT MK1's.
The P1335 / 17743 DTC code ("17743 - Engine Torque Monitor 2: Control Limit Exceeded") or ("P1335 - 35-10 - - - Intermittent") is caused when the ECU either thinks you are making >> 399NM of torque at the crank or you, in fact are, making > 399NM at the crank.
The 399Nm threshold may be higher if you have had a tune and your tuner is at least half-decent..
The most common reasons for this is a faulty MAF or manifold temperature sensor.
Less common reason for this problem are a faulty coolant temperature sensor or boost pressure regulation.
Any of the above sensors being faulty may cause your engine to think you are making more torque than you actually are (the ECU calculates based on MAF, manifold temperature, boost, injector cycle, engine speed and ignition timing; It triggers this fault if the value ends up above the expected range.
Having a larger turbo inlet pipe or a larger downpipe can exacerbate this and cause this fault to trigger more easily.
The fault typically occurs at lower RPM (1800-3000) and in 2nd or 3rd gear, although it can occur at any engine speed or gear where boost is possible. The best way to force the problem is in 2nd gear accelerating with ~50% throttle from 1300rpm up into 3000rpm.
Solution: check sensor reasons for MAF and manifold temperature with cold and warm engine. Check for sensible values in both situations. If anything is off, change that sensor.
If all sensors are okay, then either the tune is not correct or there is an issue with the fuel injection system injecting more fuel than expected.
