Newly swapped 22t block with 25d heads, using roubtune 550, experiencing fuel cut at high rpms(5 or more), wondering if anyone has experienced this? I heard it could be the maf, currently using the stock one still.

If you're using the aluminum MAF, you need to switch to the plastic 92-94 (NA) style. Also, if there's no check engine codes, I'd guess you have a vacuum leak.
