I have always driven Corvettes and have gotten burned out sooooo….I bought a Black 2005 Crossfire Limited convertible, 6speed, 35,000 miles as my new toy. Super clean....super nice. I want to spice it up a bit so first I did the muffler delete and really like the improved (to me) sound. Not what I've been used to but pretty good and a lot better than stock. Second I put K&N air filter elements in the stock location.....not convinced yet the aftermarket external filters do much but open to thoughts. Next.....and here's where I have a few questions.....I want to replace the stock throttle body for the larger AMG version. It appears straightforward and doable but my two questions are: ANY ECU CODE ISSUES? and IS A NEW TUNE NEEDED POST SWAP TO MAXIMIZE PERFORMANCE? If a tune is needed.....any suggestions on product? OR I'm in Dallas texas do you know of any tuners that work on MB SLKs?
Thank you

Welcome and I hope you enjoy your new crossfire! I would place your questions about the new throttle body in a different thread to receive more exposure.
there are a lot of great people here that I’m sure can answer all your questions on mods.

Congrats on your recent Crossfire purchase & welcome to our Forum.
Regarding the K&N filter elements, the only concern I have with using these (and I've used them for years in nearly all my vehicles until this past year) is the possibility of any filter treatment carry-over making its way over to the throttle body where it could contaminate the MAF sensor. The throttle body getting some contamination from this filter treatment isn't a major concern to me as it gets dirty enough from the crankcase breather system. Just my $0.02. For this reason, I don't use any aftermarket air filter elements requiring cleaning & treatment. Regular air filter elements can be changed yearly for minimal trouble & expense. I'm also not convinced the performance gain from filters similar to K&N are significant enough to warrant their use for everyday driving habits. Again - my $0.02.
