U should be fine with the 52 but i wouldnt go higher until your engine is built up. If you went with the 52 and you had the 5.2 liter you would lose low end, but since youve got the 5.9 ur low end should stay the same

Now I could easily be wrong; but if your going to a forced induction system I think you can go larger than 52mm. I'd actually contact the fastman, he could lead you down the correct path. With a 5.9 I personally think you can't go wrong with a 52mm.

I have a 52mm with a 50mm gasket on my 5.2 . Can't say I notice a big difference other than the ability to coast? She rolls down the road better but everything else seems the same. Had plans to build up the truck but it doesn't look like thats gonna happen.
