Redline pulls in 3rd gear no misfire so they think it's the tune or maybe a sensor is bad.
Swapped coil packs around, new spark plug in cylinder 2, fuel pressure good, compression and leak down good, no carbon buildup on valves.
Kinda wished I didn't fill with e85 to see if it cleared things before sending to shop. Need to drain or use up the fuel before switching to stock tune to see if its the tune.

When you say you swapped them, are you moving the IP Quad Sparks around or do you mean you are putting the stock ones back in?
