I talked with a guy today that had the Kleeman SC kit on his car completed, and you will be pleased to know that Kleeman with reprogramn your ecu to handle the low boost, cost is $1000
so, No more whining about how you cant' boost the N/A crossfire because the bosch ecu won't work, either step up or STFU., you can easily make your own kits for under $3,000-4,000, and another $1000 for the ecu
