Got an sr20det in a s13 with a t 28 turbo. Car drives fine upto 10psi. Then it breaks up. Cant figure out what the problem is. Got the walboro, sparkplugs gapped and checked. What else could make it break up only after 10 psi????? i am going crazy. If it was a boost leak then it would break up all the time. MAF????

dirty injectors, coil packs, and FPR. I'm sure there are a few other culprits but there's three for you

over 10psi is probably blowing out the spark. weak ignition components and/or wrong plug gapping
