If test pipes are your problem, there is a 5 dollar fix so you shouldnt worry. If you are misfiring it might be either your plugs are bad, or your coil is bad. Your best bet is to replace the plugs and find out if it misfires again, if it does then check your coils in that specific cylinder. Good luck man.
I already have the NON foulers in the test pipes but its still throwing a cel out.
My mods are:
Nismo Exhaust
Kinetix Test pipes
DC Headers
Nismo Cams
AAM Plenum Spacer
UR Pulleys
JWT intake
Technosquare reflash

What is the exact code being thrown? I would replace the spark plugs just to be safe and make sure they are gapped correctly. Just to get this correct, was your first dyno result (the high one) done before you had your ecu reflashed?
Thanks,

Wow this sucks to hear. Subscribing to see what happens after the spark plug replacement.
I thought the Technosquare reflash prevents the ECU from re-learning and re-adjusting??
Doesn't make sense to me why you're back to stock numbers... Except for the #5 cylinder miss fire code and advanced timing code, perhaps this is an indication of a problem with your cams?
Maybe you could mix some 100 octane in and see the result? Maybe the technosquare reflash gave you too advanced timing?
Just throwing some ideas out there, I know I'm not the most experienced guy when it comes to this stuff but I'm trying to help

um, yea, I think there's another reason why you're losing power and it isn't because of the ****ty ECU.

.. If it does end up being an head gasket I will return the car to stock and bring it to the dealer to check it out. Only thing Iam worried about is the erratic idle of the cams giving away the car has some internal mods.

Well to update you guys incase this same thing happens to someone else..
I put in the new spark plugs... Moved coil from cylinder 4 to #5. Started it up, reset the ECU. Same code... misfire cylinder #5. So I thought .. maybe an injector is stuck open... I then took off the Cat on the #5 cylinder and found gas just sitting in the cat. So now I have to figure out if this is def. the problem.. Working on it more within the next 15min. Anyone have suggestion to be sure this is the problem?

Have you put it on a scope yet? check your HC CO O2 CO2 NOX readings. maybe that will help your diagnosis a bit. its just an idea. or maybe a short somewhere in your injecters causing it to stay open. also if you can check your PWM to check your on and off time. if not then a new injector. once again just an input. hope it helps on your diagnosis. good luck man. now i need to figure out why my car pings!
