[QUOTE="tmhutch, post: 8286645, member: 4434"] Actually, in his case this would have skewed the results and should only be done if said mod is expected to have a dramatic affect on drivability. This is especially true for a car that has been custom tuned like his since most custom tunes over ride the cars computer in open loop/wide open throttle operation. There is some adaptive open loop work done by the computer but it takes a long time and MANY drive cycles, even than it is very little. As far as the dyno results, they are typical of other 99/01 cobras. Gains in the middle and some loss up top seems to be the norm over the years. I cant explain the loss of power up top and it seems contrary to logic but those have been the [I]typical[/I] results over the years. Maybe nobody has done a proper before and after with tuning:shrug: The earlier dyno posted in this thread is the first one I've seen with gains in the upper RPM. However, Jamies top end losses are more dramatic than they should be. Something does seem a bit off. [/QUOTE]
