I've been around the VW scene for awhile, and we own both a 1.8T and a newer 2.0T. The gains from chipping turbo motors are impressive, usually, but more often come in the form of mad torque down low, with a more modest hp gain up top. The problem is the small turbos just can't move more than about 10psi of air up at higher revs, or even if they can they simply heat up and become hairdryers, lowering power output.
So what you end up with is a diesel. Mad torque down low, and short shift around 5000-5500 to get back to the mad torque. This is exactly how the 2.0T's react (the 1.8Ts are a little different, as many were software limited up top... So most chip them to get back their upper rpm range).
I don't think I'll chip if I buy a 135, just as I haven't chipped our 2.0T. Now a turbo swap would be interesting.
Those turbos are TINY! What are they?
