(Thread Starter) |   Not Ranked : 0 score  High RPM KR Hi I’m having an issue with high rpm knock retard I’m not sure what the issue is I’m currently being tuned by DizzyTuning and at first I was having a serious fuel cut issue at 5k rpm and that turned out to be my fuel pump internals were seized inside the pump so I order a brand new pump and brand new Autotech internals and swapped out the pump and fuel cut stopped. Now my tuner is saying he’s seeing detonation up top which is hurting my power and also my boost is lower than he’s targeting (19.5psi) which could be due to a boost leak I recently installed XSPower turbo manifold and I checked it turned out 2 of the bolts were loose so I took them out put lock tight on them and tightened them they haven’t come loose again. Anyways I have no idea what’s causing the problem I took some logs after I fixed the manifold on the latest revision from dizzy. My mods are Cobb AP V3 JBR Power Path Stage 1 Short Ram Intake GPlus Silicone Turbo Inlet Pipe Autotech Fuel Pump Internals JBR 88 Durometer Rear Motor Mount 3” Manzo Catless Downpipe 3” Manzo Test Pipe Resonator Delete Exhaust Delete (Stock Piping Straight Pipe From Test Pipe Back) Corksport FMIC XSPower Exhaust Manifold eBay TurboSmart Hybrid BOV (50/50) JBR EGR Valve Delete Kit w/Block Off Plate JBR Short Shift Plate JBR Oil Restrictor Banjo Bolt NGK 6510 (Step 1 Colder Plugs) eBay Oil Filter Sandwich Plate (Oil Temp & Pressure Sensor) NRG Oil Catch Can Oil Temp & Pressure Gauge Volt Gauge Tein Street Advance Z Coilovers     Sent from my iPhone using Tapatalk |

| Not Ranked : 0 score Out of curiosity, have you had issues blowing the dipstick out at WOT? Sometimes, persistent KR in the upper RPM range can be a bent rod if the KR is unresolved with less timing and/or higher octane fuel.. You can do a compression test. If they're all the same, you might be fine. If they are different, you may need to check piston height at TDC to see if one or more pistons are lower than the others.

| Not Ranked : 0 score you may also check your vvt and timing chain if the compression is good
