Mike,

Could you answer the question above about whether it is allowable to use 87 gas with octane boost to get it to 93 for use with the superchip. Some of the small towns near my favorite hunting spots don't supply the high octane gas.

Thanks

Dear Huckster,

I wouldn't do it. Most octane boosters are crap, and don't actually do anything, and the ones that do actually work, you need 2 gallons on 18 gallons of gas to get 3 points of octane. So I wouldn't think of doing it. Also, octane booster puts terrible purple and pink deposits on the spark plugs, and shortens their lifespan considerably.

If you get into an area where the fuel is so bad that you actually experience detonation, all you need to do is to take a few seconds to pull the chip off the computer until you get back to good gas. On these '97 & up F-150's, you can simply pull the chip off by reaching up under the dash, itjust takes a few seconds, and all you need to do it to make sure you turn the truck off while you do it. You don't have to remove the computer to remove and replace the chip in seconds.

I wouldn't do it until you actually hear detonation, as usually the knock sensor system will conpensate by telling the ECU to reduce spark advance.

Good luck,

So far, superchips seems like the only choice
for my superduty v10--but I noticed something
that honestly sort of bothered (no negative
connotations though) me: on the superchips
website, the dyno graph for the v10 shows
the power leveling off around 3500 rpms
(looks like it decreases a little too)..

Now, the positve offset in power and torque
below 3500 rpms is nice, but thing is, with
a 4.3 axle ratio, I easily reach 3000 rpms
part throttle and sometimes 4k+ if I don't
let go.. so seems like pressing any
harder than that (with superchip) 3400/3500 peak on the dyno graph would be useless,
-would this mean that I'd have to watch
the revs so that when I reach the range, I'd
have to let go of the throttle to let it
upshift?

thanks for any help
