Took a minute for that to register,your're saying you hope your driveline is worse than 28% so your engine is making more than what chassis dyno is telling you.I'm from Ky. takes me a minute or two sometimes.
I hope to have mine back on chassis dyno soon to test X pipe different mufflers,I'm interested to see how much less stick uses.
