Does anyone want to tune my Riv?

So, im in the process of doing some mods... FWI is installed, downpipe is in the mail, and rockers are next. I plan on dropping to a 3.4 pully. Im going to do plugs and t-stat too. The only thing im really stuck on is a tune. I dont really feel like dropping 600 dollars on a dyno tune, and im not sure how confident i am in myself to tune it myself. Does anyone have any advice? Or is anyone close to Toledo willing to help me out with a tune? Thanks a lot for any help guys!

I wonder if you could send the ecu off to sinisterperformance and have them do it?
I know they flash the series 1 ecu,wonder if they can do the series 2? give em a call.
