I was a beta tester for Desktop Dyno (DOS Edition!). So how old am I ??? Another good one that I have used is "Engine Analyzer" from www.performancetrends. Not as easy to use as Desktop Dyno but probably more accurate. They have a good selection of other performance software as well. Looks to be HOT in Atlanta on Saturday. High for us here in Anderson supposed to be 97-98'. See you at the show EARLY!! Bruce Hevner -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
