Tuning cars that respond really well is a lot of fun. Its one thing to add a bit of timing and get 2-3rwhp its another matter all together when it drags out another 30 every time you make a change. The new 5.0’s when supercharged definitely fall into the later category. The car breaks the 400RWTQ number by 2500 RPM and averaged 475RWTQ all the way to 7300. Driving this thing is awesome. It idles like stock, and part throttles perfectly. A really terrific combo.
