It actually runs the perfect amount of timing for E30 though. My advice is to turn the boost up as much as possible on pump gas, then start turning it up more on ethanol.I'd try map 3 before moving on and really, get that flash tune and then piggy back the JB4. Stock ECU tune runs too much timing to take advantage of the IS38 on the 1.8.
Try 18 PSI peak at 4000-4500, 17 PSI 5000-5500, 16 PSI 6000-7000.
You could also flatline the boost at 16 PSI, it would still be a HUGE gain up top. You'd definitely feel it on a highway pull. Will be super stout and efficient setup.
