boost cut?

[Beems240sx]

i built a manual boost controller tonight in plan of upping the boost to 14psi. at 10psi it sounded/felt like a boost cut. i think it might be my spark plug gap. im going to gap them tomorrow to .026. is there anything else it could be? MAF voltage? my wideband is in but i dont have the bung in the test pipe, im getting it welded tomorrow. thanks guys

could you describe the cut? did you check the ic piping for leaks? how about exhaust leaks near the turbo?

Is it the stock T25? If so, 10 psi is almost max... Plus the T25 is useful til about 6200~rpm

i agree with it either being a boost or exhaust leak. keep in mind ur BOV and intercooler core can also be leaking so just because u checked all ur IC pipe connections and they all seem tight, doesnt mean that ther isnt a boost leak
