So apparently a pez supercharger tune is under scalled maf, botched injector calculation to match maf scalling being underscaled. -4% on kfzw2 and the rest is 100% stock. WHAT A FUCKING JOKE.

My attempt: upped load caps, recalibrated the load side, along with basic tuning and I can honestly say the car is significantly quicker then it was, reporting load upto 155 with no inversion AND NO UNDER SCALE

My point? We used to think that specific individuals/companies are tuning gods. Unfortunately in reality they had to clue how to do things proper so its a hack. Like 90% of the vrt tunes that exist

You're more than 8 years late to this lol.
The "cooling" is also a shitshow, the IAT is insane.

Also you should not be "playing" with mdnorm, tq limit can be adjusted in the tcu software.

I see this in the BMW world too. 1k€+ tunes that mess up the MAF and halfed timing at end of map. Or "Alpha/N" tunes that only modded the MAF substitute tables.
