NA miata stuttering at freeway speeds. Need help
As the title states, I was driving 70mph on freeway for about 20 mins, then I noticed when I was approaching a very small incline on the freeway, the miata started to stutter once I pushed down on the accelerator. I was able to continue driving at a slower pace, and it seemed to go away after a few mins of driving. Then it started to do it again a few mins after that.
Just to let you guys know, I'm boosted FM2 turbo with Link ecu, walbro 255 lpm go fuel pump, Rc 450 injectors.
Any ideas? I have check and no knocking is occurring. I'm feeling it might be too much/little fuel. Also thinking the fuel pump might be malfunctioning. The walbro is about a year old.
Any help or suggestions are appreciated.

I am having the same problem, but I also noticed that my Walbro pump was getting very noisey. Have a read at this link it may hold the answer for you. I am going back to the stock pump tomorrow, I will let you know how it goes.
