? about TRD and URD

I just put on a TRD supercharger (2014 DCSB 4.0 6spd). Would I be within safe operating parameters if I just installed the URD supergrip pulley alone. The injectors were upgraded per Toyota's instructions/parts and I have a Volant dry filter w/ ram scoop (if you can call it that).

Twice I have got a code (truck has only 6700 miles) which indicated there was an impending rich condition. It never actually tripped the code that said "you are running out of air" or "you are about to run rich. What my real question i guess is can I run this pulley (3.0" to 2.825") without any further modification?

 

I am wanting to say yes, you will be fine, but give URD a call. Gadget is super helpful and knowledgeable.

 

Id install that pump first

 

I have to second this opinion. Cheap insurance for the motor IF it ever leans out by chance. That stock fuel is on borrowed time when you add extra stuff to that TRD blower.

 

The fuel pump kit that URD sells is a pretty easy install.

 

The TRD reflash will support the 2.8 pulley. Emailed Gadget about it.

 

Not all reflashes are alike.... some run lean...some perfect.....some rich.

The pump falls off in the higher rpm and u can feel it after a pump upgrade. Where the old pump used to taper off, the new pump will continue to pull hard.
