    octane booster is what $7 a bottle? just keep a spare bottle in the trunk and if you take a road trip you're covered.

      I looked on his website but couldn't find any numbers....
      the 91 octane chip should get you around 12 hp at the crank over stock.

      I see there are some other questions here, I'll try to answer then by Thursday.

        What gains would i expect if i were to compare the Dinan to your 91 octane chip?
        I don't know how it compares to mine. They had some older versions which only had WOT maps changed but some years back they started modifying other maps. (or somehow making some chips which had other maps changed) I am quite sure that my chips will still be better anything from Mountain Dew.

              Free bump. GREAT gains from my 91 octane m42 chip. Almost makes me wish I had gone for the 93 octane option!

                    When you click "Buy," just type in the special price or instruction (or whatever) in the PayPal note to seller section maybe?

                    I'm sure you'll be credited the difference upon receipt of payment :)
