Howdy gang,

Just got back from the 'strip', and found the UD to be worth one tenth.:banana:

However, I do have new sparkplugs and a fresh change of anti-freeze, just as a footnote. But, I feel that most of this improvement is from the UDs.

I noticed when I picked up the car, an immediate improvement in throttle response, and a bit more zing, which has been confirmed.

I now must leave the hole at 800 RPM, or I get too much wheelspin. Each mod makes me lower my launch RPM. Pretty soon I will have to leave the hole at -500 RPM:D

The exciting news is that was an average time, but my personal best is now 14.67, at 97, which I feel very happy with considering it has 105,000 miles, and is not a factory freak.

Next and final mod for this season: Lidio's Race Gas Tune. I hope to test this in the next few days and have a final report for you.

Happy racing, er, I mean motoring;)

Just think, if you can leave hard off the convertor and hook up, you will shave even more off your E.T.

That's a good point, and something I was thinking about today. If the rearend was set up for good weight transfer, and I had sticky tires, I could leave at 2000 RPM, and probably shave 2 tenths.

Does anyone know where the instant center is on these cars?
