Ok guys flame away: When I get my MM this week I will only have about $4,000 to spend on any extras. I understand about the 4.10 gears and Dennis's chip. I also read that he does not think the K&N filter add anything. What would you recommend and why to improve the performance of the MM. You may email me your responses unless you want to flame But I can take the heat so please fire away. I want to get the best possible performance short of a supercharger which I can not afford.
