please help me , I install stillen gen3 intake my car too lean !!
I install test pipe on my car before 2 months , I get 288 whp on dyno jet .
After that I bought ARK exhaust and I get the same horse power 288 whp but my car was too rich 11.5 on high rpm .
finally, I install stillen Gen 3 , I get 305 whp but the car too lean in low rpm 14.7 and 13.6 in high rpm . What is the wrong ? should I remove the intake or tune ? What is the best chip ?
please help me , my car G37 sedan 7A-T 2010

It's normal, the intake pipe diameter changed and the airflow into your engine slightly increased. You will need a tune to adjust your AF ratio. Get in touch with an UpRev locally. Are you in the Middle East?

Isn't 14.7 at low rpm actually still ok. It is where you get into the higher rpms that you need start worrying right? That is what I got out of the A/F ratio deal when I was tuning my Supra Turbo
