Frankly though, there are too many variables, and It would definitely be difficult getting their tuners to repair or replace a motor after blowing it up.
Especially if they did not build that motor themselves or know the complete history of the vehicle.
The vehicle was was originally fit for purpose, so a dyno tune is to make it more reliable? but if you are adding more timing, more fuel and more boost it has deviated from its original purpose and specification.
This dyno tune was not intended to repair or fix a faulty vehicle.
I'd just add that Soichi at ST-Hitec hated tuning cars built at other workshops, again because he didn't build it. He hated getting blamed when cars came unprepared or failed, because of poor workmanship or conditions.
My own car was road-tuned, and then serviced and checked all over. before going on the dyno. In the end we only needed 2hours dyno time.
