Code P0402 After six gun install. Any sugestions?

[6.0power]

I just installed a Banks power PDA and six-gun on my 06 F350. It is awesome and I love it except for now the check engine light comes on. It is a code P0402. I have rechecked everything and can't find any mistakes that I have made while installing. Is there something that I have missed?

Mine did the same after I installed my EDGE. It went off after a while ...a day or so i drove it to school and back after and it wasnt there when i started it again ....later

I don't know if this helps but the code appears to be "exhaust gas recirculation flow excessive detected"..."egr valve position does not match desired limits based on engine speed/load" "egr vavle stuck or sticking-egr valve position bias-ep position bias"

odds are the chip is messing with something the coputer sees as abnormal, and it will probably go away with "learned stratagy" that the computer will get with driving with the chip installed.....Marc

Thanks for the advice! I am going to take off the EGR vavle and clean it real good. I had it off once and it looked nasty. I will try driving it for awhile and hopefully it adapts to the programmer and goes off. But meanwhile it is awsome with all the extra power. Its magical to see a dually burn all four tires at will now.
