pulling power ?

Gauges are always a good idea because then you can 'know' that you're not pushing your truck too far as opposed to 'hoping' you're not pushing it too far. The main difference between programmers and chips are that most programmers have 'canned' tunes and most chips have 'custom' tunes for your vehicle. Custom tunes are vehicle specific(ie. tuned for a 94-97 7.3L manual) while canned tunes are not vehicle specific(ie. all 94-03 7.3L). Chips also allow switch on the fly functionality.

Expect to see a max gain of around 65HP for a 97 with stock injectors when using custom tunes on a chip. By golly PHP offers custom tuned 6-position chips. You've come to the right place!

PHP can put custom tunes on a programmer, handheld evolution, evolutionII, evolution cs/cts. They do it all! Must be why there are so busy.
I'd say the common method of attack on the diesels seems to be analog pillar gauges and a six position chip.

Welcome to the forum!

Ok , cool ! So the the custom tuned 6 position chip , how does that work ? is it a plug & go ? What's the 6 position mean ?

The "chip" plugs into the PCM. There is a knob with up to 6 positions, just mount in a convenient place. Just click to change the tune.

FWIW, I had the 40hp tow tune on my 97. I ran that tune all the time. For my truck, the shifting and power were the best. I also had the 80 perf, whisper, fuel sipper, and lope. Even with the 80 perf, still kept it in the tow tune.

thanx guys ! apreciate it greatly !
So the the 6 position chip has 6 diffrent pre burnt tunes on it ? Can you change the tunes while driving ? is this type of chip just a plug into the PCM & go ? Thanx again !

[F-127]

Yep, 6-position can have 6 different tunes on it. You can change while driving. It is plug into the PCM and go, but that does involve removing the PCM and cleaning off the J3 connector contacts. Not like a programmer which is plug into the OBDII port.

Thanx again ! I know that the PCM is in the fender just behind the emergency break . What's all involved in cleaning the contacts ? Is the PCM easy to pull out ? Just unplug a wiring harness & a few screws/bolts ? do I have to disconect the batteries befor messing around with the PCM ? Then install every thing & then reconect the batteries ?
so the 6 position chip doesn't have to have all 6 positions filled with a tune ? The more tunes you have pre burnt the more $ ? When purchesing a 6 position pre-burnt chip , does the chip come with the 6position switch & all the hardwear I need to install it ? Or do I have to purchase that as well ? Thanx to every one , these may be kinda dumb questions but I would rather ask them then not & do somthing wrong
