I want to buy a tuner for my 7.3 litre powerstroke diesel and im leaning towards hypertech, does anyone have any feedback on it or others that might be good?
Ditto the comments. Skip the tuner and go for a chip. DP Tuner flip chip from Jody Tipton is the only way to go. Several of us here have already wasted our money on a tuner just to later replace them with a DP chip, including myself. My only regret is that I ever bought a tuner over a chip in the first place.
I have to disagree a bit here. I have an SCT Excal II tuner from Jody. Same exact tunes he puts on a chip. I use the 60hp tow program all the time because that fits my needs for towing and city driving the best. I don't see any need for a flip chip what so ever unless you just want to play. If I decide I want a program I don't have Jody can email it to me and in about 5 minutes I'm up and running on the new tune. Plus, with the SCT I have a great code reader and a data-logger.
There are several things I really like about my chip. Believe it or not, all the extra power isn't on top of the list. One of the best features - to echo mtgrzlyman and Kwik - is that I can warm it up on the stock setting, THEN switch it over to a performance tune.
As far as Jody's tunes on an SCT Excal from Jody - you are still getting proper tunes designed for YOUR PCM - unlike generic tuners that are supposed to work across a broad spectrum of PCMs.
<i><b>"Will work on any 7.3 from 99 to 03"</i> - BEWARE -</b> there are a lot of PCM differences during those years and no one tune works well for all. Jody does a great job with most of them.
