Hi,

I need your opinion in this 4th gear log. Mods are Ets Tmic, stock gutted downpipe, tp, Cobb SRI, Itv 22 and hypertech tune. Car runs fine but i dont know about the AFR. Please let me know your opinion, sorry for the chart but i could not found the dashhawk usb cable. Clutch is slipping a little bit under hard shifts so maybe slip a little under WOT. THANKS

It's a touch leaner than these cars typically run but, not really unsafe. Monitor EGT bank one temps and see how hot the turbine side is getting under high boost, then report back.
 
It's labelled "Cat B1S1". It's supposed to be catalytic converter temp but it's taking its reading of the WB O2 sensor so, It's pretty much EGT. You don't want to see sustained temps of 1500F or above.
