The variable with that question is really gonna be built around how you’re saying moderate e40 tune vs aggressive e85. I’ve seen A good handful of cars hit Max boost timing on E49 tune when getting after it hard.After a year+ of running a Vortex Std on the stock DI I caved with the Boost sale going on and PR Black Friday deals and picked up a Euro Manifold+5bar TMAP+ 3 new tunes from EQT and 925cc kit and lines from PR. I'm doing a 91 pump tune, E40 daily/moderate tune, and fairly aggressive E85 tune.
I have all the fueling requirements already installed...HPFP/Pagparts 535 LPFP/PM4
Roughly speaking, any ideas as to how much whp difference I will see between the E40 tune and E85 tune?
Yes in a nut shell - you gain not having to mix your fuels at the pump, but you also visit the pumps quite a bit more often.
