We have tuned quite a few Mclaren MP412C’s by now, but this was our first test with race gas. The car was on the dyno at ACI Dynamix in Seymour Connecticut. With drop in air filters and a full replacement exhaust this car sounds amazing! We were able to get baseline max power figures of 525whp and 440wtq with the exhaust, filters, and race gas in the tank. After our tuning we picked up an incredible 300whp around 5400rpm and 200whp max power resulting in 725whp and 667wtq!
