Ultimately you’ll need to datalog and have your tuner check it. When I first bought a return style fuel system, it was a budget system that used the Stock fuel rails. 2011-2014 stock fuel rails are NOT return style. I was rich at idle, but lean up top. Switched to a true return style fuel rail...
I had the same issue. It was locked out in the tune. With 3.73 gears, you shouldn’t need 5th gear in the 1/4 mile. Either you have a lot of wheel spin off the line, or your Rev limiter is too low. More than likely, all of your shift points need to be raised along with the limiter.

I’m in Barnegat. Not sure of manufactured date. It has zero issues. Only removed because I went with a Paxton and it was an issue for the install

I still have it. I don’t mind shipping, but the issue is, I don’t have Paypal. Previously I have sold items through JDM Engineering. I don’t know if they would do it again for a fee or not. This way they could inspect and ship for you.
Yes O/R exhaust, plugs are 1 range colder, don’t remember the gap. Lund tunes mine as well. Been working with Dakota. They’ve been great. Lund revised the tune almost 20 times, tightening it up. It still has more in it. Been short shifting 2nd gear.

The install finished last month, been testing ever since. Car went 10.2 @134 with the 3.80 pulley. Still dialing in the tune though, been having issues with the shift points. Plan on switching to 3.60 pulley, Boss manifold, Fuel system for E85. See what happens in the spring.
