Im having a problem at higher RPM's..
car runs great, pulls very hard to redline.
when i shift at higher rpms (above 5,000 when VICS opens) and i drop before the VICS cossover, the car bucks realllly bad.
its almost like fuel cut, but my wastegate is working fine (external wastegate) and my boost gauge reads 7 psi with no creep.
Mods (incase it helps)
obx manifold
external tail wastegate
stock t25r
2.5 exhaust (no cat, straight exhaust to a flowmaster)
FMIC
hard pipes.
HKS bov
relocated maf
EGR delete
new coils and plugs.
i have no check engine lights, and i can no figure this crap out, im leaning toward vics cause it ALWAYS happens when shift around the vics cross over range.
Should i remove the VICS/VTCS?
