Got my update. I must say, the power delivery is much smoother and feels way more refined. Well worth the 25 bucks. Now I'm just waiting for their $100 off special on TCU tunes.

I was hesitant to try 2.51 due to some of the comments in this thread but I seem to be fine. Flashed on Saturday and only drove about 20 miles since. Noticed the first gear surge is gone and power delivery is smoother. I have the DSG tune as well.

I'm a noob when it comes to alternative fuels and I'm kicking around the idea of the new e85 tunes to run when I'd like a little more oomph.

Can someone help me understand the science behind how ethanol fuels work? I see that the is20 is still making around the same amount of boost on e85 as 93 so I'm curious how exactly this substantial amount of added power over the already potent pump gas tunes is being made... I understand it's pay to play but I'm planning to keep the car until it quits so if the consensus is that full ethanol tunes are really pushing everything to the limit, I'll probably stay away.

Options:
  • To do full E85, I'd have to buy that tune ($225), a HPFP ($350), and update my 93 tune for when ethanol isn't available ($75) Total= $650
  • The alternative is to do an is38 on 93 once the staged is38 tunes come out. Total=$1200ish depending on the price of the is38 tune.

you increase power by either turning up boost or timing (or both). ethanol allows for more timing. at least that's what i've heard from the wizards

E85 is essentially cheap race gas. It has a very high octane as well as a major cooling effect. This allows us to run more timing to make up power that is lost with pump fuel which is knock limited. On big turbo cars this also allows us to run more boost, but our stock turbo tunes run the same boost profiles regardless.
