IIRC, Kleemann said it was fine to use the Sprintbooster with their tune. Definitely try it without and with the Piecha Power Converter before you sell it. How much is the shop charging for installation? Will you be getting a before & after dyno?
Hi James. We will call the guys that are doing the job Shop #3. Labor for the whole job, tune and headers is $1125.00 with parts at $2160.00. They are paying the overnight freight to and from Kleeman which represents part of the savings. So the total job comes to $3285.00. Although the shop has been in business just 3 mos., they came highly recommended to me by a good friend that knows them well and has used them on his Mclaren SLR and on his Mercedes Benz E63. They are actually Master Distributors of other performance products Including Innotech so it's not like they are really new to the market., they just started installs in addition to their distribution business. They stole 3 techs. from Mercedes, BMW and Ferrari. Their shop is spotless and conveniently located within 5 miles from my office. This shop is not authorized as a Kleeman dealer but can obviously get the parts.
Shop #2 came in at $1400.00 labor, $2400.00 parts plus $120.00 freight via UPS ground which will take a week for a total of $3920.00. They have been around for a while with mixed reviews but again, respected for the most part. They just moved their shop to a new home at Club Auto Sport, a very high end performance complex in San Jose where several tuners have shops. This shop used to be listed as an authorized Kleeman dealer but fell off the list about 6mos. ago. Again, they are in San Jose so not quite as convenient to get to.
Shop #1 is the actual listed Kleeman dealer. They came in at $3700.00 parts and labor plus freight but did not state what that would be. If like shop #2, then there total would be $3820.00. This shop is in San Francisco (the least convenient for me) and the indy. that I just took my car to for the B Service. They have very good reviews and also a spotless shop. But getting him to respond, quote a price, etc..... was like pulling teeth.....almost really weird like they didn't want the business. In talking it over with the owner, it was almost as if he is a "Mercedes Purist" and is sort of against any performance modifications what so ever......go figure
Originally I was thinking of getting both before and after Dynos, but each shop came back with the identical performance gains and this mod. has been done so many times on this board that I am not sure it's really necessary to spend the extra money. All shops offer the same warranty. One year parts and labor (really nothing on the tune which is actually done by Kleeman so it's THEIR warranty anyway) and lifetime (what ever that means) on the welds of the headers.
