Have any of you guys with the 650's done any performance mods? Chips, Air box, Engine upgrades....ect.....
Who makes the best chip upgrade?

I have an 07 with a 300 Cat. One of the last ones without emissions. Already got the exhaust modified.

i'd like some info also 07 pete 330 with c7 thanks bill

Last I saw the 330hp/960tq upgrade was almost $5000. You can call Chris at www.f650pickups.com he will give you the best info.

You could put a big ****ing airhorn on it....??

I had the 350hp tune done to my computer, and a intake and exhaust. The intake made the high pitch turbo noise that wa so god damb loud I had to take it off. As for the computer I sent it next day air to this place in Canada and for 500 bucks they re flashed it with a 350hp factory CAT tune. The truck was only down for 3days.

So, I guess you haven't heard the horns that I have on the truck now!!!!!
Don't get too close.....

Does nobody make an aftermarket computer program like there are for the 350 diesels?

You may not recall, but I sure as hell do - You fired them off while I was standing in front of it at JOTJ.....

My computer started out as a 230hp cat, I will try and find the invoice that had the name of the company.

John,

Call Bill and he can tell you anything about the up grades. He has done it to his 650.

C u soon.
