I just had work performed at Powershop in Enumclaw, Wa. I am always happy with their work. I just was looking for information on my upgrade results. I just had 4" Banks exhaust an AFE Air Filter and Smarty installed. They did a Dyno test to start. With no power upgrades the dyno was 191. 7 HP torque 405. 7. Second run with Smarty at level 7 was 212. 1 HP torque 470. 5 and the third run smarty set at 9 was 227. 5 HP torque 512. 0. These were the max readings. Do those results sound right with my upgrades? They left the settings on 9 for when I tow. I do notice smoke now when I put my foot into it, but I also do notice a definite difference in pulling power at 2100rpm's. From what I read I thought the smarty would provide about 60HP at the max setting. I ended up with about 36HP and 107 torque increase. I thought I would be running at a lower setting to avoid the smoke and still have some pulling power. Is 9 a normal setting for towing? Please give me your feed back.
