    I dont think he is.. He didnt install a new 02 sensor on my car, the only tools he used was his labtop and his dyno machine.. Should I ask him about that ? If so what should I ask him ?

    I got it at CarQuest. Off the top of my head I think it was 54". You might want to make another thread to find out for sure. Of call Vortech, they will hook you up.

    If I put around 3-5 gallons of 114 octane and the rest 91 octane, will that help me out when I get under 12-14lbs of boost non intercooled ? I know they say not to run that much boost without an intercooler but im afriad with the 8" that I just purchased that its going to make that much boost.. Hopefully its around 10-12 lbs of boost and nothing more.. But how can you tell, u know.. So Im thinking that if I mix both octane's together that, that will compensate for intercooler, is this logic wrong ?

    Do you always plan on running mix of 93 and race gas? If not I would tune the car just on 93. If you tune it for a mix and stop running it you can damage the motor.

    I have a simular cambo that I see 14# out of. With a safe A/F ratio and timming you should be fine.

    The tune is what will make power and keep it reliable. I just hope your tuner knows what he is doing.

    Well out here in CA, the octane is a whooping 91 !! BS !! Thats why I figure If I mix it or put about 3-5 gallons of 114 or 110 whatever it is that it'll mix an become higher then 91.. But I know what you mean about tuning the car to whatever gas you have in it.. If there was 93 octane I would be good to go..

    Belt slippage should cause the power curve to flatten out, you mentioned "divots" which sounds more like your spark may be blowing out, or if the "divots" in the curve come in at 5500 to 6000 it may be valve float.
