new chip
 

ok here it goes i have a early 99 f-250 diesel it has a 4 inch ext,banks big head,airraid intake setup it has 35 inch tires i want to order my chip but not sure of what tune was thinking of 80dd and 140 what do you guys think any help plz daily driver only

Where are you located geographically? In excessively hot or cold climates, I'd also recommend a high idle program to keep the heater smokin' hot or the A/C really cold.

I think you're on the right track with the tunes, but be warned that the 140 tune will not give you an actual 140 HP on a stock-injectored truck. You will make decent smoke down low (albeit with AB code injectors and I don't condone "smoking" anyway) but your high pressure oil pump will be really taxed for oil when under high RPM/load conditions and it will not perform very well.

I'd probably recommend the 65 HP daily driver and the 100 HP performance programs but it's completely your call.

Welcome to the forum!! :howdy:

:whathesaid: 65 is a great daily driver. 100 is fun! Maybe a tow tune?

just looking for something for better miliage and blow some smoke at the buddys dodge don't tow with it never have in 4 years so any help thanks guys
