i have an xzillarader on my truck and i was wondering if could put the boost fooler on it too. would i see more boost or would i stay the same.

 

it might be worth the 50 bucks, a few psi.

 

You should not need it with a Quad product for a 04. Should be built in. the boost fooler is for 04.5 and later. Your turbo should not have a ECM waste gate. If it is a 04 like mine.. You need to buy a boost elbo. The 90 deg. fitting that goes to your waste gate...04.5 turbo's have a waste gate the the ECM controls. I could be talking out my **** here. Better off sending an E mail to Quad
