Figured out what I was doing wrong for the boost leak test. Got that sorted and no leaks there. Did an idle log and a cruise log. I however was seeing feedback knock still up to -10 just driving in town not in boost, unfortunately didn't log that but it was between shift or in 3rd gear that I have noticed this spike in feedback knock. I realized my clutch is squeeking while pressing down and there are two plugs that I need to zip tie or something since they can move and rattle. I'll take a look at those this weekend and see if those are causing the external mechanical noise.

Thanks I'll look into a WBO2 when I get other issues sorted out. I think I am doing the boost leak test wrong as I can't build pressure. I have the turbo inlet connection to the pcv plugged and the oil fill unscrewed. Do I need to plug anything else? The pcv side I have the crankcase open to atmosphere and then the line going to the throttle body open to atmosphere. Do I need to plug that end? I am just using a bike pump to fill so it's hard to tell if/where I am leaking since I can't build any pressure.

Thanks for the input. Ill check everything over and see if somethingis rattling again. I also ordered a new pcv and inlet and will install those soon. I think after that Ill try to do the correct logs and then look at getting a tune. I don't have a wideband O2 any opinions on getting an etune without one?

Hey everyone, update: Installed new knock sensor Installed Grimmspeed TMIC Did boost leak test and all good. Checked exhaust connections and heatshields, all good. Currently have tank of gas with techron fuel cleaner in. First cruise around this is the log, skip down I am seeing -11.95 feedback knock not sure whats going on. I need some confirmation this can be tuned out and I don't need to do any other component related things first. I don't want to pay for an E-tune to find out theres other issues. Also I don't have a wideband O2, has anyone gotten an e-tune without one? datalog10.csv

I found an image of one with the end tanks off and it is just a rubber gasket sealing the edge so as long as that isn't torn, ripped, etc. clamping it closed in any way should fix the leak. Now to see if the gasket on mine is okay or not.

does anyone have the blueprint info so I can fab this up myself. I haven't heard back from anyone if there will be another batch or not and don't want to wait forever to get back to driving this car.

I will take a set if these come in stock.

Hello, Will this kit require a non-leaking oem TMIC or will it fix a leak I have coming from the short edge on the turbo side?

okay, ya I would rather be on the safe side of a tune, not trying to beat any records, just want a fun car for driving around. Okay I rigged up a very basic boost leak tester and I found out my intercooler has a small leak between the plastic end and the intercooler on the turbo side. Whats the best way to fix this? Or would I be better off with an aftermarket(which would be best?) and then get the car tuned?

One other question, I tried the 91 octane map yesterday and between shifts I am seeing feedback knock correction of -4 max what causes the knock between shifts is it just pulling too much fuel when I put the clutch in and getting lean?

Well thats good to hear a tune can sort things out. Really appreciate the feedback! I am probably going to get a boost leak tester rigged up to be sure thats not an issue and remove any rattles them ill get a custom tune. Thanks, this car will mostly be a summer car (couldmt wait till summer to start upgrading...) should I wait and get a tune when its warmer, or will the ecu adjust accordingly?

So looking at this again i missed that i am overboosting to 18.22 psi when the tune should be 16.5 psi. What are the causes of overboost that I should look at?

As far as mechanical rattle I do have a heatshield missing one bolt that I'll get tightened up however its not really "rattling". There are a few random bolts missing on random items that I'll try and tighten up. But from my limited knowledge so far the logs to me look like actual knock... but since I purchased the car after the turbo went on the previous owner I want to check hardware for issues too.(when I purchased the car it was completely stock, in retrospect should have added the accessport and figured out issues before stage 2 but...learn for next time)
