Hey guys....
I just got my truck back from the dealer. I guess all 04 Titans have gone through the problem with the master cylinder and brake booster. The dealer just replace both. $800.00 down the drain. After picking the truck up, I kinda noticed that it wasn't running to full potential. It didn't have the "get up and go" feel like it use to have. I noticed that the mileage on my speedo had reset and figured the dealer must have reflashed the computer after installing the brake booster and master cylinder. I still have the function of the three maps...stock, performance, and security, but just don't feel the power it used to have. If the computer was reflashed...do think the Titan is relearning the Uprev mod again? If it is...then I 'll drive it for about 100 miles and wait to see the difference.

I just received my copy of Osiris in the mail. If the reflash totally erased the Uprev mail in reflash mod....will the ECU accept the new mod I received with Osiris?

Any input would be greatly appreciated.:crying:

If they reflashed the ECU your uprev is gone.......
You will have to do it over.

Ask the dealer if they flashed it.

I would think if you still have an indication of 3 MAPS, by switching, that the UpRev tune is still there. I would surmise the switching would go away if the dealer reflashed, but may be wrong.

Good that you have Osiris to eventually get it back.

If the dealer did this correctly,the should have only re-flashed your ABS/VDC control unit.They are not to re-flash the ECM while doing this.You may need to verify if their access of their re-flash portion possibly removed your tuning.
Ask them for copies of their Consult II slips when they did this.

Thanks for the replies guys. I 'll check with the dealer. Been driving her for awhile now and it feels like she's getting some kick back. I guess it was relearning the tune. Like Titanblue said....lucky I have the Osiris.:cheers:
