Volvo OEM, TPS, CTS and IAT.

Status: Had some trouble with unstable readings. Coolant and IAT where sporadic. Problem traced to poor engine grounding.

Problem solved, perfect stable readings.

Tuned to 1.4 bars boost, running very fine! Lots of torque and power. approx 400bhp.

Will continue tuning later, when harder WG-spring installed.
