First some info:
My car is a 08 auto 335i e90, has 58,3XX miles, 2nd HPFP replaced @ 38,123, upgraded dme @ 38,123, and replaced 5 injectors @ 45,185 miles.
vanguard exhaust and aFe drop in filter. (will get aftermarket FMIC and maybe dp's later)
Only tunes I can compare with Eurocharged is the SSTT and JB+. While the piggybacks gave a nice increase in power, it wasn't smooth as the Eurocharged tune.
With the piggybacks i would up/downshift in DS and it would jerk most of the time, but Eurocharged feels very smooth and more powerful than I expected.
The gains were very noticeable, straight linear increase in power all the way which really impressed me.
Reason for going this route was because i did not want to go through the hassles of installing anything and wanted something tuned personally by someone instead of a generic map out there.
I am on 11.8lb of boost, and dyno'd on a low-reading dyno dynamics. so numbers will be a low.
Few minutes right after i got the tune i felt the power instantly.
here's something a little extra. this is exhaust only 335i vs FOB evo x.
(i usually don't do this, but it was for science.)

Thanks for reading.
