I'm pleased to announce that the guys at Marsh Tuning are some of the last standing, greatest og's to deal with on this forum. I contacted Mark on an inquiry of some parts and noticed how he conducted himself in a professional manner and also how knowledgeable he is. dude knows his stuff and will give you good advice as to what combination of parts you should run based on your goals. he answered all my questions and i couldn't be happier with the service that Mark and the whole Marsh Tuning crew gave me. 2 thumbs up on the whole transaction. i wouldn't hesitate to do buisness with them and nobody on this board should either. Thank you Mark and crew!!!
