Here is a link to a shortened version of the above video that hasn't completed processing yet. Tuning modifications is very important and I'm sure the engine has a lot more in it on such a mild level of boost once the fuel and spark table is optimized. While idling without mufflers the engine had an rpm fluctuation that went away as soon as the mufflers were installed. Next trip I'll try to do a testdrive with open exhaust to see what the difference is.
