Looking to add a bit more hp and smooth out my boost, so I'm hoping to upgrade the manifold. I see ********** offers the DNP. Price isn't a problem for me. On the other hand, I need everyone's opinions especially those who have done the mod. I know spooling will be a lot faster and smoother, its what I want and I'm prepared for a change, at the same time, I've heard about problems people have encountered. Boost creep, overheating, and cracking. I can't afford an external waste gate and a bigger turbo but I would like to do this mod, so if everyone can post information as well as experiences I would appreciate it. I can't afford problems, hell who can, but if one is going to come my way I want to at least know about it first.
