I just picked up a cheap e99 f250 it will be used mainly as a daily and weekend tow pig. It's a beater ex city truck 2wd. It had bad turbo I'm replacing the turbo with another e99 turbo and ordered high flow fuel fittings and banjo bolts an frx an hpx and installed a 6637 filter. I'm going to just do a muffler and cat ****** for now but I was wondering what chip or tuner I should get. I have heard mixed reviews about the e99 pcm and if I should swap it for a later one because of trans shift issues? Somebody school me on the e99 tunes if I can get a dp or ts chip and not swap my pcm I'll be happy.
