I've read reports of the uel tune getting rid of the sound but I just want to make sure before I drop $800 for a header.

E85 can be ran on a Stage 2 EL tune for stock cars safely if using the OTS stage 2 tunes. Please make sure your tune is solid and you run it for about 10 miles under 3500 rpm to allow for closed loop fuel mapping to complete. Once this is completed, you should be able to run WOT and do 3rd, 4th, or 5th gear pulls as you see fit.
If changing your tune, then let the engine remap / relearn the new composition of E% and then go from there. (It was recommended every tank you let it relearn before WOT)
Happy driving.
