However, tuned N55 normally makes peak power at 5200-5500rpm, so the peak number difference would be a little less significant, normally we see 20whp down with PWG.
As for real world acceleration EWG will always walk away because EWG has more useable PUC(power under the curve), which is 4000-6500, than peak number difference indicates.
Even an EWG stock can keep up with PWG on TMAP-only piggyback, but just you just dont just have that push you back to seatÃÂ feel at down low with stock tune.

A lot of factors other than turbo can dictate how much boost you can see. Backpressure(downpipe), octane(ethanol and meth), cooling(ic, meth), etc. Look closer, I was talking about 10+psi at 6k from EWG stock hardwares on 93AKI(98RON).
I never heard of TTH, I am assuming it’s an European brand. Unfortunately this forum is in big favor of Pure offering. Personally I know TTE(not TTH), a German company, builds good turbo for n55. Google it and check them out.
