I have NEVER put long tubes on any of my cars and not custom tuned each vehicle. Each car is different and I would NEVER trust a canned tune without checking AFR on the dyno and if you need help you can call my tuner and pick his brain.
Bruce Tucker = Tuned hundreds of Ford's via SCT.
While I agree that a tune is a no brainer, the front O2's being wideband still keep things in check. We're not saying your wrong and you are certainly entitled to your opinion about email tunes but there are also many many happy clients of email tunes, even with long tube headers and have spot on ratios.
