UDP Dyno

Don't waste your money.

Intake spacers and throttle body spacers will give the same placebo effect. Actual dyno results

If you want to get the most out of the car, intake, exhaust, TUNE!

But you still have a CVT

 

RE: 2011 Nissan Maxima CV what is so bad about the CVT?

 

I love the idea of the CVT, it should allow the motor to work at max HP all the time if desired. I've very rarely driven one and maybe they're OK from a roll, but they're not good from a stop i.e. 1/4 mile Also, their torque capacities are limited/unknown.

 

the CVT in theory sounds good, but in practice breaks very easily because Jatco didn't really build it with performance in mind.

best performance mods are simply intake/exhaust/tune, and headers when Nisformance releases those. everything else we tested either showed negligible gains, or losses.

 

Have you noticed any other side effects from the UDP? I would think worst case scenario would be a reduction in battery charging by slowing down the alternator. May not have been enough to notice.

And you dynoed the spacers and no change? Even though their site claims 12hp/15tq? Nuts...

 

occasionally power steering felt like it was struggling when not moving the car.

and yeah the spacers didn't do anything. 100's of people bought those for absolutely no reason.
