Brake fluid is at top level. The abs and traction control warning lights come on and it cuts boost and they go away and everything goes back to normal once I let up on the gas. I put a scanner on it and it showed no codes. It seems like its directly connected to how many g's I'm pulling. any ideas? its driving me nuts lol

Nanny controls don't like when the wheels break free or it thinks they are about to.  Unfortunately this is normal.

Try changing to competition mode.

Not normal. This just started happening. Also it?s happening at 60 mph going in a straight line. No traction lost at that speed.

I suggest you check the wiring that goes to the EBCM (ABS control unit) inside the engine bay. The C0900-00 Control Module Power Circuit DTC suggests the EBCM might be having power issues.
Have you cleared the DTC's? If so, did they return?

How old is your car's battery? I suggest you have it load-tested. You can do that at AutoZone etc. Remember to disconnect both battery cables before connecting the load tester.

After you: *reset the DTC's; *load test your battery *check your EBCM wiring for damage; if all is OK on these 3 fronts, then I would suggest you check the acceleration sensor. I don't have any experience with that besides knowing it is a quite sensible/fragile part. But there's a good chance the problem is one of the 3 items I pointed out.
