Hi all, I will admit I am not a huge ford fan but I was a mechanic for 8 years before changing careers 2 years ago. I'm helping out a friend who has built a pretty impressive 89 Mustang. He came to me to ask me about a good chip for his car at a reasonable price. Everywhere I go online I keep hearing about tweecer but also hear that its not very user friendly. Would like your input on this chip and just how difficult is it to set this chip up?? Forgive me if I get any specs wrong as I'm not very knowledgeable on ford high performance mods. If I remember correctly he has a 347 stroker with trickflow heads. 42 lb fuel injectors, 2003(??) cobra MAF, edelbrock performer intake, twin turbochargers among a bunch of other goodies along with a 6 speed manual tranny (i forget which one) Should he buy the tweecer or is there something else out there that would better suit his needs? This car hasn't been driven yet, engine was fired up for the first time a few weeks ago. Sounded really awesome btw. Your input is appreciated! Thanks to all!
