If you have some chassis ears put those on it. That will tell if you've got real knock. We saw the LFX reporting 4* KR no matter what, turns out it was false. Even when it pulled timing on the dyno up high there was no real knock.

Make sure I'm reading this right....sorry not trying to sound like a dummy lol. Your saying your car also pulled timing due to false knock detected, but in reality there was none and the car could have ran a bit stronger?

That's basically the issue with a lot of boosted LLT's.

Yea I understand that, and it is a bummer for sure. I was just asking if he was saying he saw the same issue on his car. sounds like that is the case.

Sort of. I wasn't there when they did this, so I hope I get this all right.

It just kept showing 4* of KR, but it wasn't pulling time. But if you are tuning it and see KR then the tendency is to believe you have some knock and pull the timing in your tune as you add boost. We also saw KR go up to about 6.5* on the dyno but there was no real knock. We think this was the dyno affect everyone talks about. We used a land & sea dynomite so we probably saw less than a dynojet would. Basically Ryan tuned mine up until he felt the could still be safe then checked for KR on the street and it was showing the consistent 4* KR but wasn't pulling any timing. So, it may be that Phastek/IPF went a little more conservative with the tune than needed because they were seeing KR and it was pulling some timing. If they listen to the engine with some chassis ears they can tell if there is any real knock as they add some timing back in.

Sean, I am willing to bet the real power is around 400 rwhp. Bring it to the track and beat up on a few V8's and that should put any doubters to rest. The customer will be happy and thats all that matters. These make power that is remarkable no matter what the dyno shows due to the KR issue. Thats why we pay attention to what the 1/4 mile results are....that is where it matters. No matter who's kit you choose, they are proven period.
