Re: Best chip for the old 7.3?
PHP for a 6 speed. Bill's tunes are perfectly smooth and linear. It will drive like stock, but more power. What kind of power gains are you looking for? If a modest gain is what you are after. Then adding just the PHP chip, exhaust, air filter and gauges, will make for a nice truck.
2002 f-350 PSD, 4x4, cc short bed, 6spd, ccv mod, airdog, AIS filter, isspro ev and scangauges, detroit TT, ITP boost annihalator, ITP RR, bellowed up-pipes, ats housing, turbomaster, 3.5 dp magnaflow, very happy with ultra smooth and linear PHP 50t, 80DD and "whisper" tunes.
