im getting a new engine (350 with 400hp) and putting on the holley 670cfm tbi and i know engines with cams need a custom chip, can anyone help me find somewhere to get a custom chip burned for me? thanks!
 
Well... tbichips.com i think is the most popular place but everyone usually says it's gonna be a best guess job, and the only other option is coming to the dark side of chip burning/tuning... which involves endless reading and a little money... I'm trying to wrap my brain around it.
 
You can check with local shops and see if any of them can dyno tune your setup. It seems to be more and more common that they can.

Besides getting into the chip burning yourself, as mentioned, that's going to be the best way to make sure it runs exactly as it should.

Plenty of good things I've heard about TBIchips.com, but just no way it can be dead on by best guess.
 
Brian at TBI chips will have you datalog it and tune the fuel pressure with a new chip - if you take the time to do so. He helped me fine tune a bit more for better overall tuning. I am quite pleased with the results.
