I have a 2010 chevrolet silverado 2500hd, i just put in a straight pipe and an Edge Evolution CTS tuner. Everything is fine except i get a trouble code "P244B" and i have the option to clear the trouble code but, everytime i take off fast, the engine light comes back on. Is there any way to evade this from happening? Your feedback will be greatly appreciated. Thanks!

 

i would say it is time for a custom EFI Live tune that takes into account your mods
