This is a maxed out JB4 map 6 in a Mustang very conservative Dyno. My GTR showed 1125 whp in a Dynojet but 900 in this Mustang (4 wheel).
So my 394 hp in this Mustang, that is with maxed out (fuel/turbos), in that case about 394/0,8 = 492 awhp in Dynojet (the one we have compared with). No more power after 5800 rpm so there is what your TCM should shift up. Backpressure (turbo hotside) is that kills all power over this rpm. If we try to go up in boost there... less power. Boost 1,5 bar (22 psi) tapering of to 1,3 (19 Psi).
I run 11,8@120 with this and no launch (60ft = 1,91). This is with E30, meth and RON 98 comparable to yours MON 93. Full bolt on´s (DP with 200 cells). We had some like ign. missings with pregapped
HKS but not after gapping down to 0,5 mm.

Conclusion:
You cant compare power between different dynos even with same brand as the shops dont adjust properly and always will make customers happy. Only Dyno that we have seen comparable is newer Mustang calibrated 4 wheels dyno. Every car showes lower figures in Mustang compared tuning in Dynojet before, still all cars considerably faster our tune. So go by times like 60-130 or 100 km/h-200 or similar where start isnt involved to compare your car. Even car by car it can differ more than 25 whp with same things.
