my mods are in my sig.. would I benefit from turning the hpp3 tuning off or not?

 

You posted this in the nitrous oxide section...so I will assume you mean should you turn off the power tune when spraying.....and that would be a resounding YES YES YES!!!!

Never spray with your HPPIII power tuning installed. Its fine for all the other stuff, but a no no for nitrous. It will give your car too much timing advance, add spray and you could get detonation...this is bad.

Hope that helps....if your not spraying, I still think the power tuning is past its usefulness due to your long tubes.
