Hello All,

I recently installed my MSPNP Pro in my 1999 miata. I fired it up, and attempted to take it for a few test drives with autotune running, and my friend and I noticed that the car at WOT would lean out. We then noticed that It was not going past 70kpa. Has anyone else had this issue? is it a mechanical issue? I was thinking it could be a vacuum leak, or maybe the car is simply not getting enough fuel, or even the location for my vacuum to ECU might be in a wrong spot. Thoughts?

 

Hey, you posted this in the build threads section.

It depends and we need more info to help you. Is your car NA? Are you at sea level or at higher altitude? What other mods have you done? Post your MAP and a log.

 

Here is my Kpa when I turn the key

And below are datalogs that I completed:
