I picked up this 99 for 6 bills and refurbed the motor to be everyday driver - belts, alt, ac, timing belt, Wtrpmp plugs but... now got the bug- so I dropped it, CA, header , flowFX . I will turbo eventually but now I'm looking to buy another ECM and socket to chip and tune . CAN I socket and chip 37820-2e-A2 from EBay and tune it while saving just CA/header settings on the original?
