Ok...so here's the deal...i have an s15 and im trying to get it tuned...i have a walbro 255lph pump, z32maf, Blitz SBC Dual Spec R boost controller, and an Apexi AFC Neo....our initial problem is that we can not get the car to tune...we add fuel all the way up to a fuel cut and it still leans out in just one area...so...we bypass the solenoid to see if its something with the controller...well that makes it stop.....it takes a huge dive right where we added all of the fuel...so i dunno what to do now.... i need some help...heres the dyno chart and were doing right at under 1.0 bar....the higher dyno is obviously with the controller unbypassed and the other is with it bypassed... on the af down at the bottom the one that spikes up is unbypassed and the one that takes a dive is bypassed...so should i get a new solenoid and see if that fixes it? or what?

Do you need the stock boost solenid? since you already have boost controller you can delette the solenoid...is your boost controler electronic?
