Hey guys, recently installed the HKS Kansai airbox with the HKS bubble style air filter. My car had a tune on it prior to the installation but was running rich (10.8-11AFR) because I also had an exhaust manifold was installed. I don't have a tactrix to datalog so my concern is that I'm running dangerously lean. On partial throttle I'm seeing 12.5-12.8 AFR on my AEM gauge and I did a few 3rd/4th gear pulls at WOT to see that the AFR is flirting with the 12.0 range. My concerns are obvious here.. so if you guys could chime in with your 2 cents it'd be appreciated

 

Get the cable and logging software. You need to find out for yourself because anything else is a guess in the dark.

 

Thanks for the input. Where's a good place to get the cable?

... or maybe track down a used one.

 

Yeah, you dont have to buy the brand new 2.0, I have a 1.3u and so far it is fine. Reflashes and logs.
