“Just wanted to let you know that I finally got to drive the AC…..The gearing feels great, the clutch and shifting are superb!!! Thanks for all your help on this… I love that T5! I’m getting a *huge* increase in miles-per-gallon, due largely to the overdrive, plus perhaps the new manifolds to let the 289 exhale more directly. And the general quality of the driving experience — to be turning 2000 RPM at 60MPH rather than 3000 RPM — is very welcome.”
