KTR/itg Maxogen Induction Kit. opinions

I have an ITG maxogen and getting it RR'ed in 2 weeks. I had a k&n 57i on and ran a 190.2bhp average over 3 runs so will let you know what I run with the maxogen
 
I'm thinking of removing my K Tec induction would it need to be remapped again if I put standard air box back on ?
