[QUOTE="Canuck714, post: 1885453, member: 6707"] The elbow is a PITA, but follow roush_14's instructions, you don't need to completely remove the back bolt. My 14 Roush was literally a month old when it did something similar. Got a JDM tune and presto...Ran 120,000 miles without it ever doing it again!! Get a tune from JDM, run good gas and I bet you will not see that issue under the same circumstances. This is problematic with a Roush tune as Roush does not re-write the trans tune to go with their ridiculously over fueled/over timed ECU tune. So what happens is the trans refuses to be in the correct gear while you are building boost and fueling the shit out of it at low RPM. This creates tremendous cylinder pressures and the ignition cant keep up. Did it still have the factory spark plugs in it when you swapped to the cooler 6510? Roush doesn't bother to swap those stock heat range plugs out either and is a bad idea for a boosted application. You may have experienced pre-detonation more so than a misfire if still on stock plugs/stock tune. Hope you get it all sorted out, once they are dialed they work really good and are reliable. I pounded on mine and never had any issues once i set it up right. [/QUOTE]
