i have a big block ford 521 ci with a modified fuel injection from a 93 mustang. i have it pretty close to right, i just need someone to finish out the tune and smooth it out. i was wondering if anyone had any experience with any local dyno shops. i would like to get the car on a dyno and tune it on a chassis dyno.

anyone ever heard of sixsigma dyno in concord? they have been really helpful with emails and such. id really like to find someone who specializes in mustang 5.0 fuel injection.
thanks
eric
 
I have heard of sigmasix but don't know anything about them. I know several tuners down in Charlotte that are very very good. Give me a call and I can get you in touch with them.
 
I'd like some info on the Mustang EFI conversion if you have a link.

all in all it's not that hard. Weld in injector bungs, get a throttle body elbow for a carb'd intake, weld in 02 bungs, I think a dizzy for a 88 F250 w/ a 460 will work. The firing order is different so it will have to be tuned for that as well as a/f mixture, idle, etc.
 
Check out custom performance in concord. He is right behind the speedway. All he does is ford engine dyno tuning. Talk to Dale.
