With a programer it will give You 3 or 4 tuning options and allow You to burn 87 up to 93 octane, that is what is nice about programer is there are so many parameters You can set to meet Your needs. Unless You are running SC You can try High Perf. setting and 87 octane and if You do not get ping burn 87 as that is what I'm doing in My 99 Silverado for 6 years and I tried it on 05 H2 and it worked also. Remember the octane You see on pump is the minimum that can be dispensed out of that pump. The octane is usually higher than pump says unless gas has aged by staying in transportation system to long or the station tanks to long. Usually it is produced, delivered and sold in days but, to be safe so they do not get fined they deliver fuel at a higher octane level than labeled on pump. My Dad's friend has a son who is an engineer for major oil co. in Houston and that is how I learned more about octane plus read the small print on the pump label. The only programer that is out at this time or being released now is the Fast Flash Handheld Programmer. You get it from Comp Cams in Memphis, TN. They have a website and You can get a contact # or email address there. I forget what there website is but just search for Comp Cams. I'm running it on My 2005 H2 for little over 2 months now and so far no complaints. I run it most of the time on performance setting and burn 87 octane no problems. I know the man that designed this one and sold it to Comp Cams in Oct. 04 and He told Me to try it on H2 should be alright, listen to engine it will tell You if it does not like what You are doing. This guy is very good and I'm confident in his work and what He tells Me. In Little Rock, AR He is well respected. This guys co. still builds the Helix Power Tower TB spacer and a air intake kit that I'm running and like both. His TB Spacer does not make noise like most. I got My Fast Flash thru the original guy and not Comp Cams, so that is why I cannot tell You much except they have it and it works real well if it is like what I got from the original programer. Comp Cams bought His programmer and unless they did some changes it should be a good programer. Hope this helps.

There are many different programmers out there. All just plug into the port at the bottom of the dash. It's even easier than installing a chip. You will have to run premium unleaded with either I believe. <HR></BLOCKQUOTE>
