Another 5,000-mile oil change done. Just passed 95,000 miles...may do trans & diff fluid again soon at 100k, plus spark plugs.

On a side note, for those who use MHD. There's a dropdown in the tunes for whichever HPFP you have. Stock and TU HPFP are in the same option, then it's DS1, then DS2.

All else equal, does changing from the stock/TU HPFP to DS2 = more power?

When the car was 100% stock, it backfired on the stock pump. Installing the TU HPFP fixed that. But I'm curious to see/hear if upgrading from TU to DS2 or even DS1 and selecting it in the tune will result in any difference.

Been running Chevron 91 octane with 1-1.5 gal of E85 but stage 2, 91 octane map.
