im having problems on the shift points. on my 75+ when I hit 49-50 its supposed get my last shift in. I can still go but then at 60 my rpm shoots up too x2500? anyone please help. Im scared to take it over 60 sounds like s in working too hard. 1. stock 2.50+ 3.75+ 4.100+ 5.140+ 6. valet. 02 f250 7.3 4x4 ts performance chip, intake, relief value, and k&n filter!

 

Shoots up? Sounds like your coming out of overdrive. Are you pushing the truck hard when this happens? 2500 RPM's is fine. Do not lug a diesel, they love RPM's.

 

Msybe thats why Im getting such terrible fuel milage locking my tc early to keep the rpms down

 

my shift points switch! seems like my diesel is overworking!

 

Again, it sounds like your truck is shifting out of Overdrive and into 3rd. Once you stop accelerating does it down shift.

 

no man...do you know what it would be. my shifts are weird it never used to do it. do you think its even the chip?

 

Pull the chip and see if it still does it. If so, then you have a tranny issue. If not, then its the chip. Send the chip to someone to get new burns put on it.

 

how do I do that and who? please more info?

 

Pick a tuner, be it Swamps, TW, beans, Gearhead, Elite, Tyrant, Di, etc... and then call them up and see what it costs for a reburn. Tell them you already have the TS style chip and just want some custom tunes... Should be around 100-150 bucks depending on who you go with.

I would do what Joe said and pull the chip though and make sure its something with your chip..

 

fck I dont wann pay so much imtaking it to the mechanic today! hope it aint a tranny issue how much does that run?
