| Phoenix Switch-On-The-Fly Chip (DISCOUNTINUED) (Disabled) Power Hungry no longer sells the Phoenix/TS chip, but if you need custom tuning we can recommend a few really good tuners that will be able to still provide tuning and support for your chip. If you have any other questions or comments about the Phoenix/TS chip, please post it here. |

Is there any De-fueling?
I received my chip today!
 and my big PHP mouth sticker i am installing it later today.... but i was wondering.... at any psi in boost does the truck start to de-fuel? also how much psi can the turbo handle (not on a daily basis but more of like a once in a while drag or dyno run)??? thanks!

Try to keep it under 25 PSI.
Nothing set in stone, but it's the general consensus. If you can hit 25 PSI, you're good.

In the higher-hp settings, that won't do anything. Bill commands the wastegate solenoid valve to stay closed anyway and there isn't a pressure signal sent to the actuator.

there is also a torque reduction map for reducing torque when the truck shifts gears under heavy throttle.. I think it defuels to do this. I know zip about automatic trannys but Cody will be able to let ya know if I am correct on how it does it..
