Nearly all of them in my experience will have spiking issues on shifts and ramp up due to how quickly Mivec brings the boost in.

Had this same conversation on the dyno with a customer on Saturday who was running a HKS EVC5.
evc5 is at least 4 years old,

try evc6 IR and you will notice the difference...

Grimmspeed is great. Easy to install, and I could feel an instant difference after putting it on with my tune
