Fuel Cut in WOT

[avillamarin]

I got the KMD internals installed a little over 2 months ago, the car was acting great until 2 days ago, as right now i did a WOT log a Maf Cal log and few fuel cut logs, it happens every now and they didnt do it in the WOT log that i did but in some logs, i notices my fuel pressure drops little by little until the cut hits and i let off the gas.

anyone have any ideas???

pls help!

PS using stage 2 93oct with IC,TIH,MSCAI

It would appear your fuel internals are no longer working as expected. You are getting huge fuel pressure drops which are leading to your cuts. The ECU is detecting low fuel pressure and shutting things down to protect you. I would suggest lowering the boost below 20psi as you're nearly at 22psi right now. This may allow the fuel pump to operate more consistently.

thank you, if i take it apart again and reinstall it might fix the issue or i just go through warranty?

I would consult with the manufacturer for any further troubleshooting. To lower boost you will need a qualified ProTUNER or a copy of AccessTUNER Race to adjust yourself. A compreshensive tuning guide is included with the software to go over some of the basics of boost control on this vehicle.
