| Well even on that dyno chart you showed there...that still doesn't look that good. Your running a 13:1 A/f at peak boost. Who is tuning this car to 586rwhp and what kind of dyno are you using? Your A/F should not dip that low, you were digging into the 9:1 A/F ratio which is just pig rich at 5500rpms and at that point your at your peak boost pressure which you should keep at a flat 11.2 to 11.8. By chance was this tune on race gas or on pump gas that you did the 586rwhp? Also..what type of boost controller are you using? Spiking to 27 then fading to 23 is a decent drop. Please understand that I am not downing your car what so ever but I'm just trying to find out what is going on. This motor that you have built, based on the modifications that I looked up should show you being in the mid 600s all day with the right tune.
