i just installed mine about a month ago. My truck had 156k on it when i put it on. I did the timing belt/waterpump, and a few other things beforehand. I just strapped mine on, and it runs great. No pinging, or anything. If you just want to run stock boost, you should be fine to just bolt it on and go. you can do the fuel upgrades later. I would recommend putting an auxillary transmission cooler on, and modifying the valvebody if you have an automatic. I now Have 160k on mine, and no problems to date.....no check engine lights or anything. This thing pulls like a V8 now
