T5 2007 1.9litre Manual LWB tranporter & Oettinger ECU upgrade

[SGG]

Well I had this done by my VW mechanic 18months ago at 15000km on the clock. I was told that I should get another 50nm (up from 250) and another 20kw up from 75 from memory.

I converted my 2007 T5 into an 8 seater (2 bench seats) for my family (poor mans caravelle) and thought that an extra 50nm wouldn't go astray. I would say the difference is noticeable but not earth shattering. Fuel economy is a tad better (its not driven hard by any stretch).

I was charged $1350 at the time ... was I ripped off ?

Also something that did happen after the upgrade (which neither my mechanic nor Oettinger upon inquiry have figured out) was at around 1800-1900rpm while accelerating there is a faint sporadic shudder from the engine bay. It doesn't always happen and its not a major shudder but it does happen and it is consistent. Would appreciate any thoughts on this as well
