i just put my car on the road yesterday. its a s14 with a s14 sr20 pretty much stock besides a front mount and an exhaust. im running stock boost off the wastegate spring. it ran fine yesterday but just today it starting missing when i get under a load. i can ease into the throttle and it will build boost put if i hammer the gas it will go for a second then just die right down in a terrible miss. any help will be greatly appreciated.__________________

sounds like the timing is off or spark plug gap may be off..timing should be set at 15degrees btdc and spark plug gap on your setup should be about 32

yes, sounds like a boost or spark issue, make sure the plugs are correct and have the correct gap, check your timing, make sure you unplug the TPS while checking timing, and also make sure your coil packs are tightened down all the way. Also check for boost leaks.
