Ok so after listening to markski i found out something! Well on the n75 there's a hose that sits in front of there well it was loose and came off ya kind of feel like an idiot. I have a video of the difference i spun 2nd damn that crap was scary. I will post the video in 30 min.

 

nice Blow off valve sound

 

Thanks

 

You have 20" wheels on your car?

 

Yes 325 in the rear it really helps me not spin to much.

However i did like the 19s also.

 

Long day today well after doing more research and Freed Performance looking it over with another boost leak test and smoke test found 2 more leaks by the manifold in the back and the boot for the diverter valve. Fixed my idle code issue also the car has no more lag anymore funny how a little leak fixes so much crap lol. I will take another full second gear and third gear pull.

 

Do you have logs of your pulls? To me it looks like as if boost is coming on lazy and the AFR is quite low at 0.78, which is not optimal for a turbo.

I do have my logs before the small leak was fixed i think hes being safe on the afr also i didn't floor it until 4k RPM.


Attached!!!

 

Ya i see your being safe also i dont have the injectors installed yet so i agree even topspeed said thats a good safe ratio for winter.

 

You guys do know im still on stock wastegates plus i did not floor it until 4k RPM!!!! I haven't put the upgrades ones on yet i bet you my wastegates are opening up to early look at the boost chart.

 

Sure, certainly on the safe side. Just not optimal from a performance point of view.

 

No problem at all. Just my opinion based on what we see here. We don't have the US fuel restrictions so that might play a role as well.

 

The log is showing late boost response, but you also start to floor it late. A 3rd gear pull starting at 2500 rpm and then floor it to almost the limiter without hitting it would tell more. If you can, also log thru the next gear.

Are you sure you found all leaks?

I personally would expect a much quicker spoolup, especially with K16s.

What fuel are you using?

+1 on the bov comment.

 

Well found out more info lol my wastegates are very weak great news lol just ordered the AMS 1 bar wastegates again remember i have stock wastegates still. I do have a leak in the back where the intake is very hard to get too it will be fixed later today wastegates show up tomorrow........

 

had you listened to me with the boost leaks 6 months ago you would not be entertaining us right now but rather enjoying your car.. lol
