I grew up in Newburgh on Evansville's east side and moved here 18months ago. If you're close to Evansville a buddy of mine from Madisonville has a repair shop, (Evansville Auto Care Center) and he's worked on alot of LSX cars. He doesn't do as much performance stuff as he used to, but he's good with LSX vehicles and is trustworthy. I think KY-Turbo on here has a dyno, and they're in Bowling Green. Speedy Dyno in Owensboro has always tuned Fords, but I believe they're branching out into LSX cars but am not sure if their reputation with them.
Also, Friday nights there's usually some people who meet up at Sonic on Evansville's north side. I will be going back there this weekend and hope to run by for a few. They were having cruise-ins downtown on Main St the first Friday of every month for awhile. Not sure if they're still doing these though. Shoot me a PM and we can meet up somewhere. I modeled my combo after yours and would love to run em.
