Bigger inj or same? Just remember the rule, you added more air in, you need to do more for the rest of the combustion cycle....Did JR send you a new chip or no? If you are running the older chip that has not been burned with the SC option, you are probably hurting on PWR! Re-burn it. Be careful with your PSI and that ATX. They are stout but you will be at limit and is your ATX new, rebuilt....? The more HP/torque you add has to go somewhere, make sure your tranny is ready and YES a cooler is a necessity.
Have fun lucky guy! And PLEASE don't kill that tour! You do and I am coming ta get ya!
