does anybody have a raptor at high alt?I got a 2002 Raptor with pro design k&n filter and just put a trinity pipe on it rejetted it at 152 on the left and 157 on the right seems to run good just wanted to know what others are runing jet wise?my altitude is 7000 feet and ride in the sand in colo and wyo and utah .thanks to all

 

7k wow! am at 4k, and used fmf slip on, chopped a hole in the airbox, and left the stock air cleaner in there. ran it on a 5 gas and it looks fine. never changed any jetting at all.
yes i keep checking the plug, and have had it analyzed as well, it's OK.
remember, perfect is the enemy of good at altitude anyway.. have fun!
check with BlueRulez about high alt stuff. he just came back from 11k high trip!
