There looks to be a gain from one or more of these parts (approximately 3%). The shop didn’t add my stock run from a while ago to the printout but below are Excel charts I’ve been using to compare various dyno runs. All up, the car is now making about 12% more peak power than stock. Peak torque (vs stock) is only about 3% up, but the gains at rpm below where the peak occurs are between 6 and 10% and the gains from just over 5,000 rpm to red line are between 10 and 20%.
