PLEASE HELP....THANK YOU

 

did you install the cams a tooth off?

 

nope

I have to?
dam........then i have to take the whole motor out again.....

 

no but your symptoms are similar to what happens when you install a cam a tooth off

 

I will check again tomw
thank you

 

checked , they're fine

help anyone?

 

If its accelerating momentarily when you downshift, sounds like boost spike combined with incorrect MIVEC tuning. Did you just slap in the cams, or did you re-tune the In and Ex?

 

an't these kelford cams bolt-on ?

 

Well, technically any mildish cam is bolt-on and go yes?? BUUTTTTT the whole point of a cam is changing your power band, so keeping your prior MIVEC settings seems counter-productive, no? I'm assuming you must be fully tuned since you also have a HKS turbo in, right?
Just to clarify, I don't know for a fact this is your issue, just sounds logically based on your situation. See a tuner (does S.F = Frisco? Hit up razorlab)

 

thank you
i am all the way in china with my evo, here we have no experienced tuner with the new EVO X..........
