Nope. Someone here posted an article at some point about how it was done by a shop with heavy work and it actually lowered torque and HP as well.

yup...i think i read the same article, and it said something to the effect of, toyota optimized the point of lift engagement, and that, when they played with where lift engages, it didnt get any better. only worse.

I thought that the XS Turbo charger came with a chip and it lowered your lift rpm? Maybe im wrong but I thought that was what was said...but other than that, you cannot.

technically you can, but as just stated (in this quote) it's not cheap plus it just lowers your performance. thumbsdown

toyota did a pretty good job determining what was the best place for lift to kick in according to the gear sizes provided. you really need to have major aftermarket performance parts added if you want to improve it any.
