[QUOTE="EFN, post: 229176, member: 1416"] Ah yes, the last two dyno run I did was for troubleshooting purpose. At that time I have installed three major "go fast" gadgets (TOM's Carbon Plenum, Apexi N1 Exhaust & FSE FPR). Being a poor after spending money on those gadgets, I resorted to tinkering and tuning them on my own aided by my butt dyno. After extensive test runs I finally have identified the ideal combo for them. But what I am not sure is if my engine is running optimal AFR for economy puprpose since my car is also daily driven. I suspect that I can still push the setup yet another stage but can't exactly gauge how much or how far - so I decided to do a Dyno session and I got the answers to my question - Yes! from the AFR curve I can actually bump it up another 2 PSI on the FPR to get to the desired powerband and still maintain fuel economy effeciency - and get another 2WHP while I am at it. The idea is to spend a lot of time to learn the car's behaviour and once you memorized them, dynoing once or two will help a lot in the margins that you have to troubleshoot them at a later stage - unless something drastic like major hardware change has been introduced so the estimation remains true. Just my 2cents [/QUOTE]
