List of what's needed for ECU flash?

I also believe that I am making over 400awhp right now with the stock MAF. I have 13t's at 18psi with 560cc injectors and 14-15 degrees of timing at the top end. All of that is a reciepe for 400+awhp. And didn't Ray make over 400whp with just an SAFC and billet DR650s?

If that's true, your maf values would be spiking like mad in the upper rpms in the higher gears.

Not saying you can't make more power. The turbos will keep sucking air. Just the maf won't be showing an accurate count anymore. Your wideband will gradually be showing leaner afrs regardless of how much fuel you add in the fuel table.
