Evo 8 mr 320 problems

[Hauga89]

Hi guys pretty new to the evo scene, hope you can help.
I have evo 8 mr 320 running around 380bhp all was well till a few weeks ago when I notice car was hitting flat spots around 4000rpm it's almost as if the boost is dropping off, this is completely random and happens most in 3rd and 4th gear, when the car hits flat spot on accelerating its will stay on its flat spot till I drop off accelerator and go back on.

Hope you can help thanks

Coil pack or plugs....what fuel you running it on?

 

[Hauga89]

V-power, plugs not long been change, turbo has little shaft play could it be that

 

[Billy MR]

I'd change the plugs all turbos have a little play

Ok I will give it ago thanks for speedy replys and help

Our best bet is to get a diagnostic plug it to give you the reason.
It could be the MAF etc...

would of said plugs would just give mis firing not causing a flat spot in power. That sounds more serious, if it wont pull after 4k if flat out. best bet as said would be get it on the diognostics and see what it shows up
