I just got my RCR stage 1 and I am installing now. Rick sent a 140 and a 150. What jet is people running in there Trailblazers with this kit? I am at sea level. Anyone? Kind of want to finish it up tonight. Not sure which one to put in.

 

you have to do a plug chop..start with the 150 and see what the plug looks like then if its too gunked up drop down to a 140. if its too white then go back to the 150 and do carb adjustments to bring it down a notch or two

 

OK I think I wil go richer with the 150 and give it a check and go from there. Anybody have to change the needle at all after geting the mixture right?
