Help with my map stuttering
 

hi all i have a 2002 1.8vvt miata with a speeduino ecu. i have a td04 turbo and 425cc rx8 injectors. im having problems mapping the car with tunerstudio. around 4000rpm and above the engine jerks and stutters and im not sure why ive attached my tune and a log of it happening.
ive gapped the plugs to 27 thou (ngk bkr7e) and am currently running 5psi until my boost controller arrives and i want to up it to about 10psi

hopefully someone can help
