Thread: Still getting knock!

Hey guys, so I have a 01 gtp and so far all I've done with the car is install headers, 180 tstat, cai, copper al104s, 1.0 zzp tune and stock pulley. I'm still getting knock at around 70mph at WOT. I've checked the engine bay for loose components that could be giving me false knock and I couldn't find a darn thing. What do you guys suppose I do to get rid of knock? My plans were to run a 3.6" pulley by now, but I see no point in doing so. The ultimate goal was to get to a point where I can run a 3.4" with no knock. So what should be my next move guys? Thanks in advance!!

what headers? if speed daddy headers did you beat the fire wall to clear the o2? if not, theres your KR.

you can but you really would need a air hammer to do it.

best check and see if its bent the o2 or not too. if its bent replace it.

if you put the car in reverse, and hold the bake, you may hear it hitting the fire wall too. your first clue its hitting.

its hitting, and zzp canned tunes are not all that. in car tune is best.

ohhhh ill have to post this on thechicagogarage.com

lolololololololol

i got in a pissing match over canned tunes with mike k.....

pfft someone having issues on a canned tune no fvcking way!!!

not saying its the tune not saying it isnt either.......

at the op please dont tell me your using a cell phone app for scanning.

2nd for the love of god why beat the fvcking firewall in? go to an exhaust shop and move the damn 02 sensor if its a concern its hitting!! plug the current hole and move the 02 is what id do but whatever works i guess nfg not my car.

just my opinion here dont everyone freak out. i dont like canned tunes, phone scanning aps, iphones, or the state of california, or the color purple....... lolololololololol

OH SH1T!!!! edit and how could i forget most importantly throw a2w intercoolers in the garbage!!!!

let the sh1t storm commence......

its like a train wreck i just cant stop looking at it.

Anyone care to show me how a zzp tune could cause this issue?

Off note, anyone know the part number of the C5 o2 sensor that can be used instead of bashing in the firewall?

181k mile engine more likely than the zzp tune..... its tired.

i say its freaking lazy not tired dumbass tunes
