Not true.
We have several dyno plots of our FR-S that show it making 165 whp bone stock with low miles and no engine break-in.
We could just as easily posted up those as the "before" and then made it look like we were tuning gods by making 25-30 whp with just a tune.
Heck we could have also posted the 173 whp dyno plots with the IAM set to 0.7 which is the default setting and shown that as the "before" showing gains of 17-20 whp from just "tune"
Point being using the before then after delta is not always accurate if the before figures are being fudged to sell the product.
