Finally tuned
hows it feel man? My basemaps were extremely rich in my setup. A few weeks ago when it was pretty warm one day my mixture got so rich around 6k rpms that my car would feel like it was hitting a rev limiter and buck at that point. Thats when I hooked up my wideband and saw that the afr was dipping into the 9's. I guess thats what I get for running maps that were tuned for 12psi with a much bigger turbo when I was only running 8psi and a small turbo. I guess it hadn't been tuned much for the lower boost. Anyways I decided I finally needed to get off my *** and tune it that day :P. After tuning I ended up with a nice 11.5:1 afr and a much smoother powerband with no hesitation at 6k anymore.
^^ Yeah, turbo size plays a huge role, I never knew how much til now. I now know the true value of tuning, basemaps really are just basemaps. My setup is a stock D15b7 with an A6 head. 48/60 T3 turbo, Dsm 450's, DSM sidemount, HKS SSQV (Which gets louder everytime I turn up the boost) 5 psi soon to be turned up etc. I wanted to blow this thing up at the track but if my built motor is ready before then I guess I'll just do some 15 psi pulls on the street
