My experience has not been too positive, as speeds of over 100 km/h [62mph for those of us who have not accepted the global standards ;-) ] will not register with the device. I would suggest looking into a hall effect sensor instead. best of luck!

Here's my thinking - the momentary hesitation when I step on the accelerator is caused because it takes a fraction of a second for enough pressure/vacumm (?) to build up to pull the door open. Lessening the spring tension would allow the door to open sooner, hence lessening throttle lag. If my theory of operation for the meter is correct (Is it, I ask?), then creating a richer mixture (via silicon) would seem to have less of an effect on getting the door open vs. just lessening the spring tension (which I now realize will also create a somewhat richer mixture). Any final comments before I give this a try - of course, I will post my results to the list. Thanks for all the pointers on getting the box open.

I have an '87 Grand National and have been a member of the GN/T Type list for a few years. I just found this list and it looks like hog heaven! Should really help my productivity here at work :-) Anyway, the GN's experience "tip in" hesitation with a MAF and TPS system, no mech. airmeter. The severity of it seems to depend on state of tune as much as anything else.
