I am having my engine rebuilt, hopefully only another month or so for parts and the like. I am looking into having it dyno tuned. Where is a good place to go. I am in St. Louis area. I know Mustang Muscle in High Ridge has a dyno and can burn their own chips. but can they dyno tune there? How long after a rebuild should I wait to have it dyno tuned or can I have it tuned right away? Lastly, I am fully porting th heads and 4-angle valve job, new cams and P&P he intake and gaset match intake to heads. Do I need a chip just to drive it safely to get dyno tuned or is the stock computer going to be alright? I know the heads and intake work changes the way Air and Fuel flow through the engine so I am not sure. Thanks.
