Hello all!! I am a new member to the forum. I also am a Dodge owner for the first time. I just bought a 1999 Dodge Ram 1500 Quad Cab. VERY clean truck. First thing i did was buy a Superchips Micro Max Tuner for it. I have it set to the 87 octane setting right now being that gas is so expensive. I am looking for other modifications to help with performance of the vehicle. I am wanting to gain even more horsepower. I also put in a new K&N air filter. I have heard mixed opinions on wherther these filters actually help or not. Anyways i am looking into buying the K&N Fuel Injection Performance Kit. Is anyone familiar with this product and does it really increase performance? A friend was telling me to change my 16"tires to some 15"s and that would also help. If anyone has any other suggestions on increasing HP,performance etc. please let me know. I however don't want to spend a fortune on this. Nothing like buying nitrious or anything like that. Just some inexpensive ways to help performance. Thanks to all in advance.
