    Yeah, They got my ECU number so I figure they'll program a Stock ECU with whatever my ECU was programmed and then dyno.

    But my concern/question is what if they show/gain something different, Then what?

    On Hondatas website it says "The K24Z7 - Si program advances the ignition, alters the cam timing and optimizes the fuel adding 4-10 ft lb across the trev range and up to 20 hp on the top end"

    * 20 Peak HP gain depending on the dyno and modifications
    * 5-15 ft lb of torque across the trev range
    * Rev limiter raised to 7600 rpm
    * Improved throttle response
    * Speed limiter removed
    * VTEC point unchanged

    I also read something where they said gains could be more depending on mods. So yeah, I dunno.

    Don't forget this bit...

    This program was not tuned specifically for an intake. Any correctly designed intake or exhaust modification should work well with this reflash.

    Which to me, sounds like an intake was not in the mix when they tuned. So who knows?!

    Here is a link which shows the DYNOmite Chassis Dynamometer I dynoed on. If you looked at my initial baseline dyno video you'll see I was on a Drive Up Ramp (Roll Dyno). Pretty much the same as a DynoJet. I'm also posting a pic as to how it varies from the dual-roller.

    You got their attention for sure Utah. Did you directly ask them, or did they specifically say that their own test did not have any mods to exhaust and/or intake?

    All the info I got and posted was off their website.

    When they e-mailed me I told them no mods. Stock dyno and then reflashed dyno. So they asked me to e-mail their support team my ECU number. Now they are going to dyno on one if their cars by the end of the week and thats all they said.

    So I'm confused what to think. Lol

    I'm looking foward to the rev hang video... that could make it worth it regardless... but not if it threatens the warranty....

    In my h22 lude, I got these results with eCtune...(SRI, ceramic header, high flow metal substrate cat., 2.5" exhaust) stock p13 (non tunable stock ecu) vs. tuned honda ecu (tuned p05/06 converted to vtec... p28?):



    new ecu vs. tuned new ecu:


    I know it's irrelevant, but maybe you guys like dyno charts as much as me... and it shows you how the h22 stacks up to the k24... butt dyno says that the civic has more low/mid range pull (maybe thanks to 6spd/gear ratios), but the lude may still have a little more up top (with tuning at least...). When the wife beats her Chronic Lyme Disease, we want to take them to the track and run the against each other. Love them all; the lude, Si, and the wife. lol. 2 Hondas and a Chrysler (wife's always broken... that accident in the ST didn't help (linked in sig.)

    The reflash itself will not threaten warranty. Damage to the engine if caused by over revving will.

    I am a dyno chart junkie so thanks for the charts by the way.
