Default Who does programming custom tune

Have a C4 1985 with headers and cam that is on the edge of needing head work. Who can program ECM prom to this application, thanks.

Heard http://www.scotthansen.net/ was good when I was on thirdgen.org if he’s still doing it if so I’m probably going to have him make me a chip for my 89 soon

Depending on what you've done, its best to find a local shop with a dynojet to do this on the dyno with a Wideband O2 sensor.

Off-the-shelf stuff really varies, but I had no problems with Ed Wright at Fastchip doing another tune for me, its just not perfect at WOT. My car runs the other chip, not Eds.

Agreed, but finding a competent shop, within driving distance, that will work on an 85's computer is dang near impossible now :-(
