Evo X has erratic boost not sure if its mivec delete logs attached

Car had a leaky bov and uicp will take it out tonight

following mods

FP RED
2.0 forged engine with sleeves
Kelford 214A
AMS FMIC
AMS UICP
AMS LICP
Mivec Delete on exhaust
TIAL QR BOV
MBC *yes I know evo x guys dont like these but works great*

Car will make a 16 psi spike around 4000 rpm then slowly creep around 5500 rpm to 17 psi then by redline to 20 psi.

Not sure if I should retard my exhaust cam gear because it has mivec delete one exhaust side its at 0 degrees right now or if I should add mivec back on to exhaust side. My car isnt a high reving car nor it makes power over 8000 rpm but it came with the mivec delete. The boost leak on it were mild so I dont think it would cause boost to have that type of surge.

Virtual dyno is showing 370 whp and 300 tq which isnt bad for a car on only 20 psi but power is just way to the right.

IIRC those come with an 18psi WGA. So, if you're running in on wastegate pressure, it seems about right. Turn the boost up..

And the X has a 3d MAP for WGDC vs TPS. You should install an EBCS and take advantage of that. It makes the car much nicer to drive.
