The spacer I'm talking about goes between the throttle body and intake manifold not in the air intake tube after the MAF. Go to the site listed below and You will see a description of spacer. It does help the low end which with the amount the H2 weighs in at it needs all the low end that you can add to it. I do not know many H2 owners who worry about top end. It is getting a brick with wheels rolling that weighs in at what 7500lbs. If You want more top end then the only real way to get that on a H2 is with a supercharger or turbo. All the different products we use are built to address a certain problem. The real problem in our H2's is lowend.

You will see other things they build. These guys have won SEMA best new product awards for several products. I have been in the manufacturing area to watch the computer controlled machining process. They do all manufacturing in house. They are serious about the equip. they build and distribute to dealers. I live about 20 minutes from them. They still build engines custom for a few people so they can test products in real world. They tease me and ask once I have blown my engine messing around could they build me a motor that will hold up to what ever I want it to do. I'm working on pushing my motor hard as I can to get the new one from them. Problem is like EPP told me that the engine I got will take allot of stress and keep going. Oh well!!

They have a new piston that will be out after more testing. It was revealed at SEMA after patent pending issued. They are still testing them not because they will not do what the piston was designed to do but, wanting to see how it holds up in real world use.

They give anyone that walks in the door advice on building or tuning a motor as long as you have come around enough for them to get to know you. They specialize in GM products but, do develop products to fit other brands. They are the only people I have allowed to work on my H2 besides Dragon or me.

The throttle body spacer is a simple and quick install. They explain the way it works. I trust these guys. They have given me allot of advice for years now when I had a wild idea. Usually my idea ended up being stuff they already to my surprise had in the works patent pending. The new piston I saw the year before they took it to SEMA just to let gearheads see it. They have just handed me new stuff to run and tell them what I think on other rides like my Silverado. They had a handheld tuner for a 2005 H2 on the market called Power Programer 2 months before anyone else did. They have had handhelds out for years. They sold the handheld to Comp Cams. The owner told me for an offer they just could not pass up. I have watched there equipment operate in a test environment to see how the product would function under many conditions.

Anyway have a look at their website and see the stuff they make and sell. I trust them because they have shown me that they are about real performance not just making stuff to throw out on the market to make money on. Many other companies handle their products. In description it will be listed as by Street and Performance Electronics which is the marketng arm of the company also the name they distribute to their dealers. Some may know that name better than the EPP name.

Mainly I'm just saying You can trust what these guys build. At least until they
prove otherwise. Just check out the Helix Power Tower Plus. I do not get anything out of this except passing info on to my Forum Buds to help all out
