First Take Gen 1 MPS with 201kw at the Wheels with factory ECU & Fuel Pump
Run a touch leaner than normal due to lack of fueling ability from factory (lean being 12.6:1 AF Same boost 17.2psi
FMIC Catted Downpipe..
Then Add a CPE HPFP to rectify supposed leaning problem...
Go back to the same dyno and loose 20kw at the wheels
For the sake of bringing AF ratio back to ~12.0:1
However
the bright side means when i actually get the ECU Tuned I have more room to breath..
Whats the highest peak boost most tuners run on these 22psi spike there for around 20 psi
or can we go higher.?
