Car was dyno'd after installing the DP. Crank power and torque was 320/330 standard and once map 6 was fettled, it gave 380/450.
I chose HFC DP as a fit and forget solution here in UK, sounds nicer to my ears than decat with mpe installed [less raspy] and any extra gains decat may have over HFC are minimal.

I had CP-E HFC on my 335 and after about a year the cats failed and I got a CEL and even AR design dps with HFC eventually failed too, so you can understood my view on then being a waste.
