Hi HansO. I'd appriciate any help you have time for. 2011 Roadster ABS with Paul Bryant Viking 3, K&N 2780s and 225 Riken rear. TUNEECU 20355 loaded, PC5 installed with Carpenter Sidewinder exhaust and RAMAIR loaded. Pipes are hot at idle with heat tape a heat shield seems to lag just for a second at initial takeoff and about 10 miles an hour. I get about 20 to 25 mpg 30 would be nice. Have a great day.
