I have the S-AFC on my car and I got the E-manage because it will help with my SVT engine switch over. Will I have any trouble using both simultaneously? I really just want the S-AFC for looks and montioring so tuning is not important on that any more. Will I run into any issues if I have both hooked up at the same time.
