Beat brand new Porsche cayenne turbo ...
About half car to 60mph from a 10mph roll, and full car at 80mph.
Mods: Eurocharged V3 tune, AFE prodry filters (carbon filter delete), resonator bypass.
Car and Driver just completed a test between the two trucks and the stock benz was 2 seconds faster to 130 mph then the Porsche.

Reasons: they both weight the same 5240-80 lbs but the Benz has more torque and more HP stock. The fact that your ML 63 has mods and didn't beat the Porsche by more says to me that your mods are not producing what you think they are.
the Turbo in the test. I didnt know you drove the 2007 ML63 (same year as my truck), very impressive speed from a great motor.
By far the best mod I did to my ML63 was the V3 Eurocharged tune. Resonators bypass a close 2nd
Any cons that anybody can bring up on tuning a NA engine? I'm looking for personal experiences. I have tuned all my Audis (pretty extensively) but never a naturally-aspirated engine so I'm not sure how reliable that is.
These tunes seem to provide +/- 30 Hp but how is the drive-ability and actual butt-dyno gains? I want to squeeze as much power out of the 6.2 without sacrificing day-to-day drive-ability or long term reliability.
Already removed the charcoal filters, resonator delete is next on the list...as well as aFe filters. Heavily weighing towards getting a Eurocharged V3 tune.
What I'm asking I guess...if you guys had to do it again...would you?
