Latest update:
After getting lots of good advice on here, my intention was to pretty much leave well enough alone...
Then after some research, I decided I would at least pony up for the screamin eagle pro tuner to so I could play with it a bit and be able to change up the tune to accomodate any mods down the road.
And after a bit more research, I discovered the screamin eagle stage 2 race kit which comes with 103" pistons, cylinders and se255 cams for a very reasonable price.... It was so reasonable that I decided I had no choice but to order it as well.
Although I was gonna leave things alone, I figure this kit is a proven upgrade and should kick things up a notch in the power department without sacrificing driveability and long term reliability.
Should be fun. Will keep you posted.
