Hello. I bought this cams (used) a few months ago. the manufacturer recommends upgraded a springs and retainers reinforced. I run with stock springs,because after reading many posts on the maximum lift on the stock springs is 11.0 and this cams are 10.5 lift. Install and run with a VirtualDyno and something wrong here: Lost low med torque and WOT with the same gain HP. The timing maps/fuel are adjust to the new cams.

The car mods:

Full Exhaust 3"
Forged
80mm intake hose
Turbo TD06 25g stock Frame
External wastegate with 22psi spring
Tephra V7
MAF
E85

EvoScan Log Stock Cams.




EvoScan Log Jun Cams


VirtualDyno Comparative (Red Stock Cams) (BLue Jun Cams)


The Boost pressure in the first log is 22 psi full and the second is 28 psi.

Help me know that is because it is very strange

Thanks Very Much and sorry my english !!

 

not likely anything wrong with the cams. highest quality cams out there.
possible you dont have enough spring but also unlikely the cause of such huge looses everywhere. if it were springs you would see sudden losses at higher rpms

this has to be some sort of install error.

 

Thanks for the request !!

I re-install the camshafts,camgear in the correct position and nothing.

Just a question: The Camshaft Position Sensor would be the problem maybe? The bolt and rotor were soft when they review all.

Maybe this is the problem or lobe cam worn out
