So I’ve got an S13 blacktop in my car and under full throttle it’s running like it has a boost leak. Sputtering and stops building boost. I’ve leak checked the whole car for any possible boost leaks and fixed any I found. Car starts, idles drives down the road fine just cruising but once I try to get into it it builds a little of boost and the sputters and stumbles all over the place. I’ve done plugs and coil packs as well as 255 fuel pump and new filter. Car runs a solid 10.0 on the wideband so it doesn’t seem to be any fuel issues.

Any insight is appreciated. Thanks.
