I sent them an email couple of weeks back asking about the same, this is what they replied:Hey, im just curious if anyone tried to change diff ratio with xhp yet? We've been thinking about fitting 3.08 lsd to my mates car, and just wondering how this option works.
Aswell if anyone has some experience with that ratio in dct, would like to hear any comments.
In all of my experimenting I have never experienced this, although I'm only at 26psi to 5000 rpm, down to about 22psi at 6000 rpm. However, I do know the TCU is extremely fidigity if you aren't reporting the correct torque values, even if you use the corrections given in the xHP software.Hi everyone! I have installed XHP software and all pareas to have been working fine. So far IO like the software, but have someone experienced gear not up shifting at high RPM with lot of power? I have had gear "locked" on 4th gear when attempting to shift to 5th gear at high rpm (over 6200 rpm) and when car is going with lot of power (26 psi of boost). This has happened to me twice. Have you heard this happened to someone else. Any advises??

As far as I can tell it does that when not enough torque is pulled prior during the gear shift, and the rpms between the box and the engine is not accurately enough aligned, so then throttle is properly pulled (if you add throttle to the graph) to match speeds, and this all leads to a very slow gear shift. To avoid this, you have to get the DME reporting the correct torque to the TCU. It's the only way I got it right, the sliders provided by xHP didn't help me.
Do you or anyone else know what I would need to disable auto shift at redline? Can I just purchase the flasher and disable it in my stock bin? Or do I still need to purchase the map pack?
xhp is calling it true manual mode and as far as i understood it is only available through their map pack.
Now has anyone tried running the stock map with just "options" changed? I am just looking to stop upshifts in manual and change the diff ratios
I am excited to see improvements in xHP...
