Lots of carb tuners out there for sure. My suggestion make some calls and see who is willing to work with you and do what you want done. There is one on here Dominic Thumper Carbs. We work with Dale Cubic closely but more because we have a personal relationship with him. AS far as carbs nothing is better than a Braswell IMO but they come at a price. But anyone named here can help..Just DONT call Pro Systems
