The entire install was handled by the Stillen Service Department. Since we had already run Blue Bomber on Stillen’s DynoJet dynamometer after the supercharger installation, we wanted to be able to scientifically quantify the changes created by the installation of the performance exhaust parts. Back to back on the same dyno under similar conditions gave us the smartest results. With an ASE Master Technician installing our parts and tweaking the computer’s tune to accept them, we knew we would be happy with the results from Stillen. If your truck could use more power, give the pros at Stillen a call.
