Note: Used with Hypertech tuning Pro: Noticed improved horsepower in the 3000-4500 Range Part provides adequate gains. Cons: Install nightmare! I am a GM technician, had to put lower intake manifold gaskets in my 2001 Sonoma. Thought I would put the V-Max in while i was at it. Here are the problems: 1: The 14mm bolt in the back of the driver's side head is very hard to remove. If it is seized, I don't even want to think about it... I used a couple of different midget wrenches to get it from underneath. YOU NEED A HOIST FOR THIS! 2: Even after removing the hold down bolt for the fuel lines, movement is minimal. Reattaching the fuel lines from the chasis to the CMFI unit is a challenge. Not enough length. *GM Recommends replacing the O-rings (not supplied) from the fuel lines to the CMFI unit each time they are removed* I do not have a leak issue at this time, but you have been warned. 3: Various bolt are the wrong length, and size. Have your own supply of various fasteners on hand. They give you an M6 to replace an M8 a time or two. New studs for the throttle body are too short. Not rocket science guys. 4: The new position of the fuel lines can cause an issue with positioning of the spark plug boot on the distributor cap (clearance). 5: Removing the CMFI unit from the upper manifold can be tricky, as I know from experience. Be very careful not to damage it or the manifold. Getting it to seat back into the upper intake manifold is also tricky and takes patience(to prevent a vacuum leak). I did it on the bench since I was putting lower gaskets in at the same time. On the truck, likely much tougher. 6: The PCV tube has to reach another inch higher now, with no provision made for it. Make sure it installs securely or you find a way to anchor it. Bottom line: It works power wise, not sure about economy or longevity yet, install sucks and not enough thought was put into how the spacer affects distances and clearances. Not an amateur job.
