I have a 2003 F250 7.3L. I would like to do the high idle mod to it but have searched the website and found nothing so far. Any help would be great. Thanks.

 

Ok, I will give you the heads up on this one. Get a DP-TUNER and have Jody put the high idle on any number you want. jk not really but you will find out soon enough.

You have been a member sense 2004 and this is your 9th post? Where have you been?

 

Rick,
I have been married to my new company that I own for the past 3.5 years and have had to give up my modding for a while. IM BACK NOW! LOL

 

Good to have you back. Let the mods begin.

 

Rookies. Get married to the company, by all means. Have a mistress or two on the side.

 

Get DP tuner F5 chip. Dp Tuner. He will put a stock tune in #1 and high idle in #2 and so on. Question, why do you want a high idle?

 

I have it -- it's nice when you need to run high-current accessories or keep the AC ice cold in hot summers.... Works great!!!

 

I also use mine while giving someone a jump start, instead of holding down the go pedal.

 

Heres a link for a DIY. Its in there in the electrical.Tips - Idea - Hints This one is for the OBS trucks so I'm not sure if it works on the newer ones. I had seen another right up else where but dont remember where. Also there is a site that sells a plug and play deal that goes in the harness for the go pedal. Dfuser sales a AIC. I'd just save my money and go for the DP but its all in what you want. Hope this helps!

 

Another vote for the Dp tuner

 

I own towing & recovery companies and my trucks need to idle fast for the jump starts that they do, extended idling, as well as keeping the A/C cold on those hot days down here in the south. I personally drive an 06 F-250 with the 6.0 PSD. The high idle mod for this truck was SIMPLE. I was hoping for the same type simple deal on my 7.3 but it's looking grim..

 

Is that all the high idle mod is for? I thought you got a power increase some how. Well coolder A/C is always a good thing.

 

Yes, you do get a power increase -- out of the alternator. At 700 rpm, the alternator output is low. Bump it to 1200 and it's nearly full output.
