Increasing performance on the 1700 is addressing the restrictions. Putting on a K&N filter will slightly improve air flow. Installing something like Chucksters Intake System or a Thunder will improve it even more, and you should see a increase in mileage/performance. The engine however, is still restricted by the exhaust. Either changing the OEM slip-ons for less restrictive ones or drilling the baffle plates in the OEM units will open up the exhaust. Again, an increase in mileage/performance. But now an already lean-running engine will be running even more lean, resulting in the dreaded after-fire racket. A tuner will not only resolve that, but also increase performance by giving the engine the proper amount of fuel to run efficiently.
Annnddddd I'm now collecting lunch money for my tuner, so I can attest to the after-fire!
