since a throttle body spacer serves no purpose on a fuel injected engine, if i got Justins custom tune to go with it, then would it perform like it should??

 

i don't want to come accross as rude but didn't you answer your own question?? since the throttle body spacer serves no purpose on a fuel injected modular ford then no a tune won't help the throttle body spacer

however a tune will help your truck alot

 

so Justin couldnt tune the modular so that it injects more fuel along with the TBS injecting more air??

 

I'm not being rude, I'm going to be completely honest with you. The TBS (Throttle Body Spacer) does nothing for the vehicle. It does not inject more air into the motor. Justin will tune the vehicle to acheive the most amount of power out of it. It's not a matter of tuning. It's a matter that the TBS sucks !!

 

the throttle body spacer does not help the truck get more air, the cold air intake does and the tuning will help your truck optimize performance.

DO NOT WASTE YOUR TIME INSTALLING THE THROTTLE BODY SPACER!!!!!!
