I know nothing about these things, and the FAQ doesnt really mention them much.

I know I need a 4 bar to push 18+ boost, but when i searched for one they had two different types on offer, angled or straight! Which do i need for my 03 180FWD?

Thanks people.

 

The 3-bar will work fine for your setup. The only time you need to upgrade is if you increase the MAF diameter, or go to a BT setup.

 

you only need a 4bar if the tune calls for it. Plus you shouldnt be messing with mafs that the tune is written for either,

 

Thanks guys, gonna keep what i got then!!

 

Thats good. The reason there isnt much info in the faq is because there isnt much to write about it. you basically use what the tune is written for or to increase the cc of the injectors if you are trying to lower duty cycle or use something like 380cc on a 440cc program
