Sputtering on WOT..

timing, maybe? did you change/alter ignition?

Check a/f. Is it warmer now than when the thing was set up? Sounds like a blowout or something.

Sounds like a vacuum leak, check all your vac lines including your IC piping. Or your ignition coil could be going tits up. Hard to troubleshoot....what boost are you at when the sputtering starts?? Does it start as soon as you go WOT?? Or is there a RPM related??

Sounds like misfire...what are your plugs gapped at?

I run 6 heat range NGK-Rs with .028" gap withno issue - but I ran some Accel wires for a short time and the car did EXACTLY what you're describing - Lots-o-misfire. Swapped back to NGK wires, and I was golden.

Dunno why yours would just start happening, but...?

Rob at 10 psi you need to check you’re timing and maybe back off on it a little. And are you using a CAT? If not, think about some tuline to run a little higher octane. And as for the WOT problem do a compression test and tell us the results.Just to be sure.
