NO

The BTM is just to retard timing for boost it doenst have a rev limiter. The 6AL does.

If I remember right, the stock ecu has a fuel cut off at 6250 rpms.

so whats the point of the pill it has a spot for it

The 6462 box has a chip limiter built in but no it will not over ride the stock computer fuel cutoff. If your car is boosted have the factory limiter shut off, last thing you want is the computer pulling fuel under full boost.

You do that in the tune. You will need to have the car tuned to play with anything the the ECU. I looked at my BTM (Vortec model) and I did not see a spot for a pill. Just the wire harness and the vacuum nipple but I can't see the bottom.

He's got the 6btm which is the 6Al with the btm built into it. So it will have the soft touch rev limiter. What you probably have is the plain btm which is what comes with the vortech kits.
