Non acvs. Ej207 heads,ej205 intake and harness. 

Upon first startup i recieved a p0340 and p0171. Cleared it came right back so i decided to take a ride.bad bucking,no power, backfiring,  i used the cam sensor that came with the heads. Timing is good. 

My question is am i going to need to go straight for a tune being im running different cams than the computer knows? 

SOLVED.  Jdm cam gears are not the same as usdm. The sensor will not read the jdm gear. Solution: Swapped the gears over to the usdm ones (yes timing marks are still the same aswell as keyway)
