The A90 Supra arrived carrying the weight of the Mk4's reputation, and the first question everybody asks is whether it lives up to it. We developed our software for the car on our own dyno, and the first thing that development turned up had nothing to do with tuning at all: the car was already producing more than Toyota quote for it in standard form. That is common on the BMW derived engines, and it is exactly why we run every car in standard form before we change anything rather than working from the brochure figure.
Measured on our Mustang AWD rolling road in Maidstone. Wheel figures, drivetrain loss added for the flywheel numbers.41 years ago, Toyota introduced what would soon become their most popular sports line. Fast forward to 1993, and a legend was born wielding the very same name; The Mk4 Supra. Not only was this car ahead of it’s time in the 90’s, it remains to be the most sought-after JDM cars. With its extremely underpowered 2JZ engine, owners were quick to tune the infamous block to 4 figure horsepowers with ease. That’s exactly why everybody was excited at the announcement of the Fifth iteration of the Supra back in 2019. We’ve spent hours with the A90 Supra tuning on our Mustang 2000HP Dyno developing our software to unleash the car’s true potential. Can we help the A90 Supra to live up to its predecessor?
Stock Results and Figures
There is a lot of controversy around the Toyota and BMW partnership for the Supra. But it certainly doesn’t take away from how impressive the Supra is! We first run diagnostics checks on the car to make sure that everything is running as should be. We do this before changing anything on the car so that we can be sure everything will run smooth after mapping. Factory figures claim that this car produces 335 BHP and 500 Nm torque. Whilst these figures are impressive, we run every car on the dyno stock to see what it is actually producing. When we put this Supra on the dyno, we discovered it was actually running higher than the stock number with 369 BHP and 572 Nm torque. That’s 34 BHP and 72 Nm torque more than Toyota quote! Differences like this are to be expected, especially with the Supra having the BMW 3.0L Engine as most German cars show the same trend.
At JFA, we love all things JDM. That’s exactly why we were eager to find the true potential of the car after tuning!
A90 Supra Tuning: The Results
After many tweaks and adjustments being made to our software, we were finally happy with the results this car was producing. On the last few dyno runs, we found that the Supra was now running an impressive 442 BHP and 664 Nm Torque! That’s just over 100 BHP and 160 Nm Torque more than Toyota claim the supra makes! As with all jobs we road tested the car to ensure everything was in order; it felt like an entirely different vehicle! As you can see from the dyno graph, the torque band shows just how different the power delivery is throughout the entire rev range now.

Questions we get asked
Why do you run the car on the dyno before tuning it?
Because the quoted factory figure is often not what the car makes. The A90 we developed on read meaningfully above Toyota's claim in standard form, which is common on this engine. Without a standard baseline taken from your own car, any after figure is guesswork about where you started.
Is the Supra really a BMW underneath?
The 3.0 is BMW derived, and that is a large part of why it responds so well. It is an engine we already knew from the BMW side, so the calibration work began from familiar ground rather than from scratch.
What will my Supra make?
We will not put a single number on that until we have seen your car. Standard output varies noticeably between examples of this engine, so we run yours in standard form first and give you a printout of before and after rather than a figure taken from somebody else's car.
