Tuan

Setup : JDM Type R B18C engine (Spoon cams, v springs,cam gears,exedy clutch, Jun ECU and a vtec controller)
Dynoed my car recently; got 148 whp... at 8,800 rpm.. There's a huge dip right at the vtec x' over (5.300). Torque is around 15.2.
My mechanic advanced the intake cam by 3 deg.. do u know what exacly is the problem? Thanks in advance..

your ecu is causing that dip in vtec switch over.

We dont have any AF readings here in Malaysia... I didnt change the vtec x'over point.. The Vtec point is 5300(Jun ECU).. Should i retard or advance the exhaust cam? What is the optimum fuel pressure for my car?

Cheers
