This was assumption, as the difference with k04 is huge regarding pull even tho im driving with base boost.
From the info i have found the safe point is 300tq

A single K04 can't do much more than 200-250 anyway

Anyway, i have read on this forum, where some member, had gt2860rs on his 1.8t with stock rods , prj incl others told that he had probably already bent rods, so that made me cautious. If the difference is so big compared to k04, wont be impossible i think.

I would say no detonation looking at piston, but cant be sure beacuse scrap from piston skirt has damaged top of piston.
File was stock, only: underscaled MAF, LDRXN/LDRXNK in all area 255, KFMIRL same 255, and little work on KRKTE

And all that on 95 octane

When i made log it was -12 retard all time during WOT  Shocked

So here is my afr after today run. Ofc i run out of maf at the end, but before changing to bigger one i would like to dial the fuel with this maf. Is thiss considered rough ?  Is this fixable in HFM ?( dont mind after 5000k, thats where maf is 5V )

There is no good reason to use an external controller. I should hope he's not that silly.
