My engine actual spec is:
K26 hybrid (same as Albert sold), RS2 EVO manifold (style), RS2 IC, 3B->AAN conversion with mafless setup. Maped boost is 1,8 bar and should hold it to the redline. Dyno result was ~400ps and ~480nm torque - shame but true. Plan is to change the IC for bigger.
Unfortunetely after few monts of runing good it now drops boost at higher revs (0,2-0,3bar). This couses loss of about 60-50ps at the dyno (messured now 340-350ps). There are no intake leaks, timing is good, no other issues.
What could be the reason of loosing boost at high revs? Worn out WG? Something else?
Regards.
