They haven't given much more info than the basic marketing graphs, I hope I'm wrong but I don't thing they care about the 2.5 market any longer to give us any more. We have to figure things out our selves, if we want the info.
I don't have installed, I for one don't think it's the greatest thing since sliced bread, just what's available. The power is made high up above our redline, if that's what you want then the money is worth it.
Apart from my track days I wouldn't be using the high rev range much, the 2.5 has a habit of throwing off belts at high RPM. New pulley and tensioners were promised to fix this but I haven't seen them for sale.
UM and IE are probably the last one who care of the 2.5 market in term of tuning. A guy swapped a DSG and UM is working on the ECU to make the DSG compatible with the ECU
They are also the only one, as far as I know, to make custom turbo tune and they stopped making turbo exhaust manifold since the one from Bluewater performance is almost identical ^^
As for the 02q, it's almost done, just have to install the GTI shifter and the shifter cable, install the left axle and drain and fill with new OEM gearbox oil, we are doing it on free time, it should be done by next week (Wednesday maybe)
And a picture
Edit: the shifter box of our 5speed is the same than the 6speed, only the shifter cable and shifter cable end links are different, so we took the end link and the mounting bracket of the GTI and we put it on the 5speed cable, I have been told that the 5speed cable is a bit longer so I would need to swap it, we will see once we test the car.
Other than that, even if the 6speed seems bigger than the 5speed due to the size of the differential, it does fit on our car, we have enough clearance, here is a pic from the view of the inner fender on the left side:
It's almost done, I should have my car tuesday if everything is fine, 1 bolt missing (a m10x105x90, but I bought it yesterday), I should also receive the gearbox oil tuesday, I discovered that the oil of the 5speed isn't the same that the 6speed, I think viscosity is the same, but there is something more in the 6speed gearbox oil (it's like 40$cad/liter), I got 2L even if the trans needs 2.3L, I will fill the rest with 5speed oil (I have 1L of 5speed OEM gearbox oil in my garage), it shouldn't be bad.
