    The McLaren 570S in stock form is more than enough car for most people considering it runs low 10's at 135 miles per hour. If you were most people you would not be reading this site. How does the McLaren 570S respond to tuning? Very well. The M838T V8 is hardly pushed in the 570S and it shows with these results. The baseline with race gas blended in produces 503 horsepower and 508 lb-ft of torque at the wheels. Very solid baseline figures on a Mustang dyno: Add in a downpipes and a Stage 2 DME Tuning ECU dyno tune and the car goes to 588 wheel horsepower and 582 lb-ft of wheel torque. Race gas improves these figures even further to 608 wheel horsepower and 619 lb-ft of wheel torque but you will notice the gains mostly come from 3500 rpm to 6200 rpm. Toward redline the race gas and pump gas curves level off and mirror each other as the stock turbos look to run out of breath. With a race gas tune and downpipes the 570S will be running deep into the 9's at well over 140 miles per hour. In other words, it should be able to go up against the 720S big brother.

    The E46 M3 CSL originally made waves because it managed a stellar 7 minute and 50 second laptime in the hands of Sport Auto. Back in 2003 this was a quick time. For perspective, a 997.2 Carrera S PDK on Michelin Pilot Sport Cup tires matched this time in 2008. The CSL was spectacular. BMW shaved 240 pounds off the car for a total of 3053 pounds and managed to squeeze 360 horsepower out of the 3.2 liter S54 engine with a new airbox design and a new cam profile. Not to mention the suspension, aerodynamics, and brake upgrades. The E46 M3 CSL was BMW M at its best and the peak of the classic M brand. That 7:50 Nurburgring time was an incredible achievement. Now in 2017 look at what this E46 M3 is doing. A 7:28.5 and yes it is still naturally aspirated. The M3 has a CSL airbox from Karbonius Composites and a CSL tune from Chris Benoit. This of course is in addition to the suspension, brake, aero, and tire upgrades. An absolutely phenomenal result when you factor in the E46 record holder is a supercharged E46 M3 CSL running 7:22 and the a stock F82 M4 takes 7 minutes and 52 seconds. The driving probably has something to do with it.
