ultimate tuning performance?

[72Ford250]

Ok guys we found this cheap chip and if it works it will be great but if not the seller will take it back no ques. asked and pay for shipping so here it is DIESEL CHIP TUNER FOR 1997 97 FORD F250 7.3 POWERSTROKE: eBay Motors (item 180541897305 end time Aug-10-10 05:28:11 PDT)
I want all of your thoughts on this product good or bad Thanks for any input

I would not do it,with the added power you still need to tune your trans for more line pressure and also I don't believe 5 mpg. Just stick with a good tuner like dp or any of the other tuners that are on here.

From the looks of it, it is just a pressure box. Adding resistance to the ICP sensor.

Does this change anything horse power wise or gpm wise?

The truck is a stick so no trans tunning to do

Looking at the picture and description it looks like it just "modfies" data the ECM sees from one sensor. Definitely not worth it in my opinion. There are a lot of factors that come into play and modifying one sensor just ins't the right way (most efficient, safest, or most power) to do it. Save up for something a little better.

I don't think it would work for the 99' and up 7.3's, but for the earlier 7.3's this is basically the 10k mod by placing resistance/resistor on the icp sensor which can give you good power. But I have no clue how much resistance is in that box....

SO what does it cause the engine to do? think that is cold air out right witch results in more fuel delivered or less? and doesn't it cause the engine to re time right?

This is for a 1997 powerstroke i posted in the wrong section

I would guess it probably is like the 10k mod. In which case there's plenty of people that use them. I guess it's a matter of perspective, but I would rather spend the extra cash to actually get some tunes. Just the difference I noticed going from a tuner with "canned tunes" to custom tunes tells me it's worth saving up and getting a tuner/chip.

does anyone have a link to a 10k mod thread?
