Our custom tuning can be made for stock or larger injectors and increase power up to 40 RWHP (varies with application). The FICM will need to be removed and sent to us for a bench flash. This is not a repair or exchange service so any module sent to us will be what you receive back. MAKE SURE THAT YOU SEND A GOOD FICM as there are no refunds of custom tuning. Price includes ground return shipping. If expedited shipping is needed, please call us to place the order.
