drops to only 26 up top

 

Can anyone anwser me on the afr's and how this chart registers AFR's, when he wasn't monitoring AFR's through my LC1?

 

If it wasnt using a wideband, then those are not the actual AFR numbers. He may have been logging AFRMAP, but that is not actual AFR.

 

ok cause at WOT I see 11.1 on my LC1 and it holds there which is still rich. He probably just tuned me to be very safe and conservative. I did mention that I was nervous about WOT it. Last time I did it the engine went boom.

I'm boost leak testing this weekend and going to check for exhuast leaks.

 

You should try to get your tuner to lean it out a little and get it to have more torque!

Also those HKS 272 are mild go with GSC S2 or Kelford 272.

 

Well some things have been discovered. Cracked header welds on the bottom side of the ports. Thats why i didn't notice any exhaust leaks. Hidden cracks.

Noone ever purchase the Tomioka header. I found about 5-6 leaks at the head and turbo. 650.00 manifold is garbage.


I just sent off my stock header to buschur for the port/coat with all new grimmspeed gaskets This time i'm going to use the copper RTV and seal this thing. I did a boost leak test and everything checked out there all the way to 30psi

 

Well I fail epic at boost leak testing. I didnt realize how slow the boost is suppose to fall and I found a major leak that i missed on my lower intercooler pipe and on the back of the throttle body where some allen key plug is?. It's starts to leak really bad at 24-25 psi.


Retune time ahead once all is fixed

 

This is the BISS screw. Are you sure that it isn't the throttle body shaft seals that leaks?

 

i replaced the shaft seals less than 3k miles ago. Those are good to go.

I can put my finger right on the biss screw when i have 30lbs in the system i can directly feel and i can make the leak sound change with finger pressure. its definitely coming from that
