Fear not though, you can upgrade to a larger diameter tube and recalibrate that MAF, or go with a MAF that will read a higher frequency and calibrate that MAF.
Trifecta should know what to do here. I'd start with the V8 MAF, I believe that would be a good place to start.
The MAF is not being maxed out. The readings were higher than what the ECM could process. We made good progress this week. Car is expected to go in the shop for some work on the front facia so hopefully we get this wrapped up soon after. Will update again in about a week or two. In the meantime, I'm sure we'll have lots to discusss with Jims results.
