98 eclipse running lean at 4000 rpms

[222deuce222]

my 98 eclipse that I just bought and it cuts out like it over rev at 4000 rpms and when I ease into the car it will open up fine. I have no idea what it could be but my car is turbo ( greddy) ( s-afc II controller) could be a boost leak or something. I also need help with this same problem. I'm new to this and bought the car with everything installed in maryland a week ago. Its not running like it has bad gas or bad spark plugs either.

anyone have a idea of some good settings for my car or where i can find some settings for my safc II?

Start with basics run a boost leak check. If you dont know how youtube it there are plenty of turorials. And you need to be more specific whats the current set up ?

everything is stock i believe except the turbo greddy kit, it also has custom settings already on the s-arc controller too but i dont know how to use that either. I am very new to this stuff and kinda just jumped in. Im not for sure how many pounds of boost it is pushing either. Don't know how to see how many pounds because the greddy boost controller doesnt have numbers.
