I do agree to a point, the research has been under way for a couple of years along with many reports of users findings and it really isn't hard to figure out if it corrects throttle lag or not, the question is does the throttle lag bother you or not. The questions about performance that keeps coming up is still answered the same way-- the SB does not increase HP or 1/4 mile times and cannot be measured by a Dyno as it is only to correct inherent drive by wire throttle lag and it does a GREAT job of it. As to the high cost, in the world of Sports cars $300.00 isn't a very High cost item.
