ok so whipples arent bad its just that they are meant to be the only mod to an engine,and if you want to go further into it they arent very willing to help, thats not too bad because i dont plan on going all out on my truck. but what about the one in the classifieds it came off a 99 will it work on my 06?

 

I have the same whipple on my 99 and the instructions are for 99-06 vortec 4.8,5.3,6.0. Hope that helps.
