I am putting these two mods on my truck. I will keep you guys posted as to the gains I see when I install them... I am just waiting for a few more miles before I get a baseline dyno on the truck, I am only at 400 right now.

 

less than a year after i put a chrome mac cai on my 03- the inside rusted out -flaked an f-ed up my maf-mac is less expensive for a reason-phil

 

Does not matter to me because I am going to have the tube powdercoated to match the paint. Thanks for looking out though....

 

MAC parts are pure crap. I think they buy all the rejected parts of other manufacturers, slap on new stickers and resell them. I know their mufflers are just flowmaster ripoffs. I would personally stay away from them.

 

What mods do you have that are making 400HP without a tuner and intake?????

 

400 miles, not hp....
