Considerations:
Fitting a new exhaust will require dyno tuning to optimise both fuel and ignition. Just fitting alone could result in a lean mixture and lead to engine damage if ECU not adjusted. We offer dyno tuning.
We can provide a Base map; however, this will not be optimised for your engine and will leave performance unlocked.  It quite common for identical setup to have fuel requirement 20% different to use other.

White Ford fuel injectors supplied with the blacktop Crate engine will be close to max duty cycle, and its noted that any further modifications after fitting 45MM Throttle bodies could result in needed to swap out for a 3.5bar Fuel pressure regulator or fitting larger fuel injectors.
