I have a question for you guys, maybe you can help me. when i fire up my raptor (2007 700) it idles good but when i blip the throttle, it revs up great then dives way down low before returning back to normal. any ideas what might be causing that? i have tried multiple tunes on my PC3 but still same outcome.

My mods are Sparks X6 Big Core, Pro Design intake, PC3, JE 12.5:1 piston, Hot Cam III, and Bo's track P&P....If someone has a PC3 map close to that could you email it to me at [email protected]. There are some close but they all have a +3 TB bore which i dont have yet. Maybe my map it off down low or something. Thanks Guys

Back the idle air bypass out about a half turn and see if that helps, or open up the throttle plate a little but then you'll need to readjust the TPS and idle air bypass.

Does anyone know how many turns out the idle air by-pass is stock?
