Well I recently got my first D-max and already the bug has hit me to start the upgrades lol. Right now it's just stock with some junk 90hp hypertech tune but I picked up a proflow air horn and downpipe along with a PPE boost valve that I plan to put on when it warms up. My buddy has EFI Live and is a very good tuner so I'll let him at the truck once I have all my hard parts. I'm still gonna get an exhaust, gauges and... The lift pump lol. Thus leading me to my question. I'm looking to make about 500 RWHP. Should I be looking at a raptor 100/150? And what pump is better... A raptor or Kennedy? They both seem to have good reviews both around the same price. One thing to keep in mind is it gets really cold here in winter and diesel can gel up which seems to burn out weaker pumps, or so I'm told by my duramax buddies. Help please... Seems no matter what I read I can't decide lol
