Boost Stutter?

[bfeng24]

I have a 240 with an sr20 swap, it drives ok, when i reach higher rmps in each gear it seems to stutter (around 7-10 psi), its not really a hesitation. I just replaced the maf with a z32 but that did not help. Any suggestions?
Thanks

Get back to the basics

Plugs, wires, timing
Fuel filter
air filter

Check all of that forst.

Are you having any CEL codes?

when you swapped in a z32 maf, did you do anythign to compensate for the different pinning ?

but what was already stated, start with the basics. sounds fuel or timing related.

sounds like you're blowing out spark. lower the plug gap to .028 you should be running an ngk bcpr7es or bkr7e.

Sounds like either a boost leak or spark blow out.

Yep thats exactly the problem I had. Plugs were too hot. I put in some bkr7e plugs and problem went away, runs great now.

Definitely try getting some colder plugs.
