I've just recently completed my "stage 1" mods and need to tune My PC-V right now it's based on the 255 SE cams and slip-on mufflers as Jamie didn't have any maps for my cams. My mods are in signature, my exhaust is 1 3/4" stepped to 1 7/8" 12" out from port into 2 1/5" collector followed by 24" supertrapp w/ 20 disks (now) all ceramic coated silver. It's really lean part throttle at 3000 rpm, almost unridable w/o any disks. My problem is money is short now and my budget only allows $300-$400 now, so do I buy an Innovate hand held wide band O2 data logger and tune it myself open loop (I have many other vechicles that this tool would be usefull on), or buy Auto Tune module for Automatic closed loop tuning, or take it to Rolling Thunder (based 2hrs away in Joplin, MO) a reputable dyno tuner for $200 one time custom map? I plan to do head work over the winter and possibly larger (maybe cable operated) throttle body. Is it possible to make the throttle by wire more responsive so that it "feels" like my hand is connected to the throttle body? sorry post is so long. no matter what route tuning I take I will post results and share my map with anyone interested.
