David Shoup calibration
100* day in the shop made for a fun time keeping IAT's cool but the car still managed to perform great considering.
As always, with a precise Shoup calibration, you can expect a safe and reliable flex-fuel tune that unlocks peak power on E40-45 fuel blends. This tune delivers a very wide powerband, resulting in exceptional throttle response and increased area under the curve.
Don't let the numbers fool you - while dyno sheets can be subjective, the real proof is in the performance. This car delivers impressive power, capable of rolling burnouts in 3rd gear. On the street, it runs exceptionally smooth and correction-free, showcasing its fine-tuned state. A recent VANOS adjustment even yielded a notable 20whp gain!
David implemented a custom redline with a new hard cut rev limiter, eliminating the restrictive 2048 limit that previously caused power loss near the redline. The result is a significantly smoother transition into the next gear, with minimal power drop.
Next up are upgrades to the high-pressure fuel pump (HPFP) and S58 injectors, followed by a retune. This should unlock a significant power boost, with expected gains of at least 75whp.
Big thanks to David Shoup for working above and beyond standard working hours so Greg could get back in his supra!
