Default Active Handeling System mode

Help.

Was driving home from the airport yesterday and the car went into Active Handeling mode. I pulled the codes this morning

C1278
U1160

P2100
p2150
p2110
p2115

I've just installed an STS twin turbos and had some problems with the MAS so that has been replaced.

I was alos running my track tires NITOS NT01

Fronts are 275/40 ZR17 with at 25.55 diameter
Rears are 315/30 ZR18 with at 25.35 diameter

I selected Competition mode and things seemed to clear up.

Could the tire sizes begiving me problems?

I only use those tires normally at the track, just had not taken them off this time. I'll run them off in comp mode then move to a better sizing mix.

thanks/George
