My 100k AGU has excellent compression over all 4 and made 160 hp on midland Vw rollers.
185hp after map.
That was as it rolled out the factory with supermarket fuel.
Definitely feels quicker with all the usual bolt on bits and always Vpower.
I agree, just a couple of days ago my AGU with 100k on the clock made 165bhp before any sort of map on midland vw rollers. Made 189bhp after map. Also it doesn't have any mods except a cheap ebay resonated catback.
After checking my turbo is in good condition. No cracks. Wastegate however is a little weak. Needed some preload.
Issues i had was heatsoak.
However i have thrashed it on the road and logged through VCDS. Inlet temps aren't too bad, quick to reduce, and absolutely no pulling on the timing. A good map.
