I really need help on this guys some are saying its in the tune and some arnt. the fuel pressure goes up to 55 at the rail when you turn the key on and dreps to 43 at idle when you get on the gas it comes back up between 52 - 55. the exhaust leaks are gone and the temp runs steady at about 180 unless its really hot outside. I am going to change the fuel filter again tommorow and might throw a new set of plugs in it.

Look at my post above... If you want help answer my questions.

that has nothing to do with it, it is knocking as soon as it pulls any boost. I dont have a reading for lbs of boost all i have is the stock boost guage

You're right... boost has nothing to do with KR.

Good luck figuring out what your issue is.

It knocks as soon as it goes into boost and it varys but it definately climbs with more boost it goes from 1 - 3 at half on the guage to 6- 10 at wot which is horrible. I have been fighting with this thing every since I put the engine in and apperantly everything I have tried hasnt helped. I have installed three superchargers two fuel pumps and two throttle bodys I have also removed the headers 6 or 7 times chasing the leaks. Luck has nothing to do with it if you arnt here to help stay off my thread because all you have done is show that you think you know what your talking about so far. Everyone likes a little azz no one likes a smart azz

Tried helping you by saying 20 posts ago that I thought it was in your tune pending more information. When I asked how much boost you saw you told me that wasn't the issue...

It looks like you've addressed multiple mechanical possibilities. My best recommendation would be to have the tune checked out. I would try and find someone to do a custom tune on the car.

Well we tuned it yesterday and alot of the knock was in the fuel trims so we got a bunch of it out by maf tuning. We took some timing out of the P E mode but it is still pulling 5 - 6 deg pf knock from 3200 - 3600

**thunder71173** · 06-15-2011

re sealed the lower exhaust joint today just to make sure and replaced the plugs with new 104s gapped at .050 still knocking away at about 6-8 between 3200 and 3600. The fuel is spot on or within -5 +5 either direction.
