I'm getting a custom made 3" MAF. What setting should I use on the EU? Would it be the same as VQ35 owners? I think they are using Q45 settings?

Within the next few weeks I plan to get this bad boy installed, along with the NWP Spacers, Power valve removal and Megan Catback system. Then hit the dyno for proper tuning as I have emission testing coming up in few months. I was hoping to get the Cattman Fastcat but it's on backorder. Any other recommendations on a Hi-Flo cat?

 

Random technology HFCs are available for our car.

I has Megan Racing Test Pipe

I have a custom 3" maf as well. I left it as the stock settings and just added fuel so it runs at 14.7. Then I went ahead and tuned everywhere else

 

Thanks Kevlo. I'll try that and see what happens. Do you recall how idle was once first installed?
