hi, i have a 07 mustang GT with a HPperformance stage 2 turbo kit mated to a livernoise block that has been in the shop for a few weeks due to tuning. The shop said the EMS is going haywire under high boost 24psi. I own another turbo mustang it is a 93 GT conv my first car that whent together like bread and butter its on 8psi stock block for a few years now, no trouble. Is the shop BS me? I live in San Diego and have never seen or heard of a turbo mustang around here so is it just lack of exp?
