attemped to install pes t-28 turbo kit, but the 45 degree oil return line connector was the wrong size. i installed a temporary workaround with an adapter found at home depot, but after the rest of the kit was installed, the ecu was not responding. i shipped the ecu back to pes and they installed a new chip on it and shipped it back with the correct oil line fitting. the ecu was still dead, so they sent me a new socket and chip. i replaced these in the ecu and the car was finally running after 7 days of downtime.
