pick up an aftermarket engine management system, such as an electromotive, or a haltech. An electromotive, is alot cheaper than a haltech tho and jsut as effective.
Its tough running boost on a stock ECU.
even if it is chipped.
Because that chip will only give you a certain map to work with, no different than NOT chipping it, jsut as difficult.
with an aftermarket EMS, you have total control over your map, to not detonating your engine, and getting the best results.
