LTFT High, Stock Tune and Stage 1 93
 

So after running E85 for a little, I decided it was time to go back to 93 because I was taking a long trip, and E85 would be hard to find. I switched back the normal way, and my LTFT seemed a little high, but nothing outrageous, so I kept going.

I am now about 4000 miles past when I switched back, and I cannot get this LTFT and STFT to normalize. I have used the Stock tune, and the 93 Stage 1 OTS tune.

I did a pull. 1st through 3rd. If you look at the LTFT, as soon as I get off the throttle, it jumps to around 15.

Just a couple minutes of normal driving. At one point, I jabbed the throttle and Knock Correction kicked in. I was told the stock tune allows some knock at the higher RPMs

Im thinking it may be an Intake leak? Or maybe an Exhaust leak.

Do these numbers look bad, or should I be fine.
