No problemo!

 

Comprende.

I'll try the other tunes next, then go back stock, see what happens, while I'm trying to get Bill.

I work at a Ford store; any point in getting a PCM update/reflash? My svc mgr will do it for little $$.

thank you!!

Randy, the PCM update MAY help things, but your programming will still be in the RXDG family. However, if you can get a "deal" on it, I'd do it. You definitely don't want to have the truck reflashed AFTER you get custom tunes, because that will make those tunes invalid and you'll have to pay to have them rewritten. So, do it now rather than later.

Great, thanks.

I have put in a service ticket at PHP, in fact Cody has already responded. If I understand this correctly, I will put the truck back to stock tune, have the PCM updated, then let Cody/Bill know if the HEX code changes. Correct?

Don't mean to be a pain, but I want to make sure I'm going about this correctly.

thanks!!

Randy

 

You're on the right track!

 

Yes, Randy, you're doing it right. Make sure PHP has your new hex code after you get the PCM flashed. You'll see it as soon as you plug the programmer into the OBD port, so be prepared to write it down.

Thank you all for the great help, I'll keep you posted.

Two tanks on canned 87 tow, runs stronger, better throttle response, picked up prolly 1/2 mpg.

Back to stock today, low speed clunk gone.

Next week, new PCM flash, new plugs, clean TB and MAF. I'll prolly run a couple of tanks through just to see what that did, then back to 87 tow, then hopefully get my custom tunes in a couple of weeks.

thanks!

i have an RXDG hex and i'm running the canned 87 tow tune on the evolution. i don't really have any issues. i had an issue with it surging a little around 1200 RPM while driving under 40 and a really rough idle one time but both have gone away.

 

...took about 2-3 weeks, as advertised.

Two weeks on 87 Tow, stronger, better throttle response, all shifting and clunking concerns gone, and picked up .5 mpg to boot. Switched to 87 Perf yesterday, power feels about the same, shifts are smoother.

Mag SISO, Gotts, and Gryphon: changed the whole truck. Far more fun to drive and went from 15.5 mpg to 17.5 mpg. E-fans next.

thanks to all!

Great to hear

 

thats awesome. i am still waiting to get mine back from being upgraded. It has been 3 weeks today. im hoping it gets done soon.

 

That's good to hear!
