Hi and welcome Viper.
I dunno why but I'd take your car, if you don't want it anymore...
I also like the rims and your choice to remove the SEC-stuff.
It looks like a lot of work and a bit money.
Also the new painted engine looks nice.
What was your reason to take the DTA S40?
"The car has been on the dyno. 171.5rwhp and 210nm"
Hmm isn't that a bit low? Are your sure that the compression was right when you dynoed the car?
I think you should earn about 40 PS/nm more with an EFI.
Good luck with finding the problem, hope it's nothing expensive.
Regards
