Dyno records can be misleading. The truth is that most people regard tune X as better than tune Y if tune X is making more power. Unfortunately, most people just look at peak figures. PTF (ProTuning Freaks) is running around claiming a Toyota Supra B58 tuning world record with the dyno pulls below.

Is PTF superior to every other tuner in the world? Of course not. Are they better than AMS Performance for example who got less peak horsepower out of their MKV Supra? Not a chance.

AMS took their car off the dyno and proved their tune in the real world on the dragstrip setting the Supra 1/4 mile record. That is very different from increasing timing on ethanol to eek out some more horses to claim a record for marketing purposes.

Tuners go about things in different ways. AMS Performance prefers to set records on the strip and this what real enthusiasts value. Real world, proven, performance.

PTF already had B58 motor failures pushing OTS tunes. Their OTS tunes showed more peak power than most competitors. So what though if the engine did not hold together?

Making power on a Dynojet which is not load bearing but inertia based is completely different from applying that power in the real world and more importantly having the motor last with the tune. Any tuner can hit this peak output with the B58 on the factory turbo like PTF did. There is no magic they found in the turbocharger. Maybe there is a reason literally all other tuners are not pushing to hit these figures?

Is this a game of playing with the safety margin with some ethanol for Dynojet glory numbers or a real world proven reliable and sustainable performance level? Frankly, it needs to be proven off the dyno.
