You guys did right by providing a link of where to look.

 

lol!!!

 

have a 2.2 auto,bought a jet stage 2, paid over $250 for it, easy instal, but it didnt work for me, no measurable 0 -60 or 0 to any speed improvement, even used premium fuel for a week as suggested by jet tech, ill lump it in with other cheaper chips on ebay , worthless junk, i did hear on other forums of a tune tyme,power tune as working great ,must send your ecm out to them, it makes me a little nervous, if i do it ill post results

 

I have the stage 2 chip and run the premium gas. noticed more throttle and more rpms. I also have the cgs intake and magnaflow exhaust. but i am wanting to find a dyno and get exact results

 

may be. what year is yours? mines a 2.2 auto 08. i use timed track results same place ,temp, 0-60 ,0- 100 and quarter mile,my base line was 0-60 in 9.1, NOW with pulstar plugs .muffler completly gone ,no jack or spare, and airraid cold air intake. mobil 1, im down to 8.3 secs 0-60 ,quarter mile shaved a half second, LATER after the jet did nothing,all times the same, yes it shocked me as other jet products usually work, i know 07-08 hhrs had a slight power boost to 149 HP, the 08 battery looks at least 5 lbs lighter than the 06 i had,dyno results are hard to come by for the average joe,they are only in big cities. thats why i do stopwatch runs
