I don't have a throttle delay. When I step on the throttle the engine responds. Now if I'm at too low an RPM the car can't respond because there's not enough torque, but that's driver error. My engine is stock with the plugs at 0.035". I run 91 octane.

Really didn't believe all the hype about a few thousandths making a difference.

So while my oil was draining I decided to regap my plugs. They were .026-.029 so I bumped them up to .032.

What a difference. I only took it for a short spin, probably a half mile there and back. It sure seems like that 2-4 second delay is gone from the initial take off.

I will know for sure while I'm bombing around for work in the ol' girl today.

For a gas mileage improvement I would of bought it but not for a hp gain. A very cheap mod I can live with.

Thanks.

Comments like this make me wonder what GM gave up when their lawyers told them to set the "official" plug gap at 0.028 instead of the original 0.033-0.035". Yes, there are tradeoffs in any engineered system, but when lawyers and accountants get involved everyone loses. Look at what happened to Pontiac after deLorean left.
