Wow that's good to know, thank you sir! Do you know if the Eventuri intake would cause that by any chance?

So under throttle what does the car use if it's not using the MAF?
I haven't heard if it does or doesn't. If they copied the factory flow it won't. The BMS I take flows a lot more so it causes little hiccups like that. I just like that it wasn't a factory clone.

Actually the DME BT and ECU psi aren't as far off as I thought. JB4 is probably just learning.

The factory DME targets up to 14-15.5psi I believe. Hangs in the 11-12 range most of the time
