He mainly worked on the quality of the idle and partial throttle. He found that the Autolite 3924 plugs I was using weren't working very well with the setup and were causing a popping noise in the exhaust, so he switched to a colder NGK plug (what I wanted to run in the first place but couldn't find any info on them) and the problem is resolved. He did, however, find that the #1 cylinder spark plug is getting contaminated with oil, and since the compression checks out OK, he suspects a bad valve stem seal, so I will have to replace those before the final dyno tune.Also he suggested that I place my IAT sensor POST-blower for more accurate readings, and suggested that since I am not running an intercooler on this setup that I look into a methanol-injection setup to make it "safer" for those increased temps.Other than the minor issues/corrections needing to be made, the car drives WAY better! It idles like a champ at stoplights, cruising RPMs it doesn't seem to hesitate or run 'sluggish'.. Thus far with the tune (before WOT attention) I am very happy with the street manners of the car.</blockquote>
