IA3+ issues

I experience sometimes with my stock ECU.  If I really lay into it I'll see
1.8 pretty regularly but when I shift, boost is limited to 1.1-1.3 or so
until something sorts itself out.  

I've noticed my IAT sensor has an extra set of wires running outside of the
sheath off to somewhere.  Haven't tracked that down yet.
