I would like to know exactly who I should speak with in regards to tuning a bone-stock 2004 E55. I live in SoCal in Temecula, I frequent OC quite often.
Also, I have spoken to Vadim at European Performance in regards to having headers, mid-pipe (secondary cats delete) and x-pipe installed next week. I would like to know if I should deal with anyone direct with Powerchips for the tune? In doing my due-diligence on the variety of competitive aftermarket companies (e.g. Renntech, Evosport, VRP, Vadim's shop, LET, etc.) that offer similar parts, who is truly offering the best "package deal" right now?
Is there a difference between Vadim's 175MM pulley and the 180 offered with VRP and Renntech...and the 182 offered from LET? Any advise would be very much appreciated
!
A gentleman who drives a 2004 Z06 at Evosport (who was very nice and willing to talk) told me that anything over 172MM pulley is overkill because the car will "bleed boost" if too large of a pulley is installed---so what is too big?
Lastly, what is the quality like with the 82MM Throttle Body that Vadim is offering, and is that the same one VRP has? Does it compare in quality, performance and overall longevity to the RENNTECH one?
Thank you in advance for answering any of my questions! It is really reassuring as a "NEWBIE" that this site is here to obtain questions, products, and meet cools MB Owners--LOL
