i have had my ecu mapped by someone local to a 'stage 1 tune' but the car is making to much boost, near 2 bar everywhere on wot until 5k where it settles down to 1.4 bar. i looked on the s4 wiki but am still not to sure on whats needed to correct/lower the boost

anyadvice will help on what maps to adjust

i have attached original and modified bin where i have added left foot braking and higher rpm limiter

Start from stock file, find a proper definition and DIY. All the info is here, tune is probably just garbage.

8500rpm rev limit on stock head? lmao. My advise would be remove this from the ecu, throttle filtering disabled kfzwop/2 and kfzw are %% increased, bad changes in irl, kfped has values lower then stock in the 60%-100% range, iop has unneeded %% changes, bts fueling disabled, kfldrxo zeroed, ldorxn ffed, lamfa is too sloppy and too rich for stage 1, imx %% change, drl %% changes, and i was roughly only half way into the file. didnt need to see any more. If I was you Id ask for my money back.
