I just installed a Volant CAI and went to my neighborhood exhaust shop and had them build a Magnaflow exhaust system (dual over the axle )...the truck seems ok.but hasnt pitched a CEL ..yet...but a buddy of mine will tune it tomorrow with HP tuners....Think things will be pretty schweet....

 

Well, me and my buddy data logged yesterday on HP tuners....and Jim could not believe that the trim on the air and fuel were perfect...after all sorts of driving his recommendations was this..." this will cost you money and you may gain very little power and fuel economy is a crap shoot "....so ,I probably will let it be..
I do notice the drive ability seems smoother after the intake and exhaust..the tranny shifts seem to come a bit sooner at normal driving speeds..which drops the rpm a bit sooner...which may help out on fuel economy.
