Currently on a e85 basetune from dave. Boost leak my car to 22-23psi with no leak. But still at 17-18 psi. Even with pump gas I’m around there. Tried turning the boost up on the i3 but nothing. Could my pcm be limiting me to 17-18psi? It’s a stock pcm. Also I have a S2 wg. Would flashing my vin to like s1 or S2 help?
