Just have a code reader ready so if you do start experiencing misfires you can tell what cylinders they occur on and then start diagnoses (usually the coil goes first).

I am at 800 ft elevation and 93 octane and was concerned running anything above 1 o'clock. |

Must make sure always 93 octane. Hell you can squeeze some E85 in and feel the difference! 30-35% ideally. |

Good quality 93 such as Shell, 76/Phillips66, Valero, Costco, BP or CITGO (TopTierGas.com rated) Adding 3-5 gallons of E85 to your 3/4 tank will give you more performance and keep your IAT temps cooler with the more aggressive psi + (perfect for drag runs)

I just installed mine tonight. Is the difference supposed to be immediate or does it take awhile I don't feel much difference if any at all
