The car is a chevrolet corsa 4 cyl 1.6l 8v with forged pistons, forged connecting rods, a modify cam, intecooler and oil cooler. The cr is 7.5:1
The turbo is a Garrett T3/T4 journal bearing at the time boosting 5psi because I'm runing the OEM fuel injectors (160 cc/min).
Im using a MS-I v3.0 MSnS-E with the stock VR sensor and wheel decoder.
Its a wasted spark with 2 VB921.
I will get news when it run seriusly boost.
