    There are no cons to the 2 bar upgrade.. For boost you really should do it. Easier to dial in the VE, and if I remember right it extends your maf table, which you will need.

    I would do a billet shaft at this point but it really shouldn't break so easily. Does the tuning school still turn off the torque management ? If you did that then put TM back in the tune.

    I would try raising the regulator offset. Try something like 75 psi and see if it helps.

    I am no expert but on my car I increased the airmass by the approx. percentage that torque has increased over stock. Never had an issue doing it that way.

    Ran MAF only on my car for years and it ran perfectly so I have to disagree that maf only cant work. I didn't look at the tune yet but will when I have a bit of time later.

    I have a fairly similar trans build and don't see anything too far off in the tune. I would try enabling the upshift adapts. Not sure why that's disabled.

    I really don't know enough about it and should learn. I delayed the injection until after the exhaust valve is closed, and it helped big time.

    Dead cold start this morning. A little surging in the idle but I can give it gas or shift into gear and it doesn't stall. Definitely huge improvement. Now I will recheck MAF and VE and fine tune...

    Thanks for the suggestions.
    I am going to look at these possibilities as soon as I have some time. Would that emc12199 table effect only cold start like that ? I have never played with those.

    Is there any point in raising this now that its available and will it cause any other changes to the tune ?
