Hi guys!
I've been building my car for a little over a year, was 2.8 atmo a4 b5 1998, and i did swap 2.7tt bes from allroad 2003, with 01e 6 speed manual gearbox, aem 50-1000 fuel pump, pfr7q candles (0.65mm each), bosch 1000cc injectors, rs4 maf, tfsi coils, and etc...
I'm trying to configure my car for stage 2, following the example of Nyet.
But my boost is not constant, it decreases all the time, and traction is only present at the start, in the first 3500 thousand revolutions, after which the car no longer pulls as well as I would like.
According to the logs, I see that car reaches the set values, but cannot maintain them, there are no rollbacks when igniting.
AFR keeps from the given 12.5 (from lamfa map), approximately 12.8-13.0.
I've been adjusting the injectors for about several hours, and they still need work, which is probably why I can't achieve the desired result in AFR.
Before, I didn’t create topics on questions that I had, and I always tried to look for similar topics of discussion, and everything worked out, but in this case I’m at a dead end, I’m hoping for advice from those in the know Smiley
I can pay for help if required, cause I appreciate people who develop and respect their knowledge and time.

I forgot to add, pop'n'bang almost doesn’t work, I tried dozens of different settings, made more than 15 cars using my bang settings, and everything works great for everyone with or without flames, but on mine car you can barely hear anything making noise from the exhaust.

You may want to use vehical, my tuner will not have me use anything else. Its a lot easier then me7logger, free for me7, and will give logs that are actually usable.

So you need a different cable. If you can't make logs, nobody can help you.
VCDS does not produce logs suitable for tuning on ME7.

PM's will not be answered, so don't even try.
Log your car properly.
