Thanks to all for the replies. I guess I am still thinking of cars/trucks in a pre 90's mind set - before computers and design skills have eeked out the efficiency we have today. As far as driving style? I am as light on the gas as I can be and still get the thing moving. I do tend to cruise at 70-75, which I know sucks more gas than at 55, but accept that as the price of fun.

Ok, so more HP seems to be the question? So how do we get more out of a monty? I found a set of headers, and flomaster has a decent muffler that should squeeze a few more out.

Does anyone know of any other performance mods readily available? Chips etc? I've searched high and low, and have not found much
