3rz supercharger question

Hey everyone,
Installed a supercharger on my 98 3rz with a low boost pulley. I upgraded the pulley with one from URD that delivers around 6 or 7 psi. I also installed "pink top" injectors from a later model Tacoma. I DONT have an afr gauge installed yet.

My questions are do I need to upgrade my fuel pump? Do I need a piggyback for the ecu? If the afr gauge reads ok then I'm fine right?

Thanks for your input.

 

At the absolute minimum, I'd run a piggy back ECU (think S-AFC II or equivalent) and an AFR gauge.

To be safe, get the thing on a dyno. Have a shop tune the piggy back with the AFR gauge. That will determine if you need a bigger fuel pump.

 

What piggy back would you recommend that doesn't cost a fortune? Can most dyno shops tune the ecu? Thanks for your help.
