fuel cut issue!?!?!?!?!?!
i installed a new fuel pump, fuel pump assembly, and filter and thought i fixed the issue of fuel cut. I am still having issues.....
Also changed spark plugs, coil packs, injectors, map sensor, and checked the timing. Whenever i try to go past 6k @ wot it breaks up and hits a wall and loses all power. Looks great up til that point.
Possible things that could be causing it. AEM EMS 1052u has bad injector (things)? dunno the name. actually inside the ecu. the ecu data logs look okay and everything looks fine i nthe computer, but when we put a load on the car it seems to die. When we engage vtec it dies all together. when unplugged it goes up to around 7200 before it dies...
i am seriously shit out of ideas... help me please......

can't be wastegate lines, because i pulled the top one off and it was running off of the spring which is 7 lbs.
can't be 2step since that only works at a dead stop to my knowledge, boost cut is set at 12psi, and its not rpm cut. My tuner knows what hes doing and has tuned multiple s2000s. its not the tuner. I know this has something to do with my car lol.
I'm thinking about just pulling everything off selling it and just running it NA. I'm pretty sure that the turbo kit is the issue here lol.... vacuums look fine, everything looks normal to.... i'm just confused as hell.. wasted like 200 bucks on the fuel pump replacement when i didnt need to.

i hope its somethijg as simple as a gapped spark plug... to be honest i dont think they were ever gapped by the tuner. if it is a gapped spark plug issue i hope they wont charge me to get a "retune" since it wasnt my fault and they shoukd have fixxed and known to do that. i also had an oil leak after getting my whole motor rebuilt and stuff but they replaced all the lines and it isnt leaking any more., but my car is still smoking frol.all the oil sitting in my exhaust... it will smoke every npw and then, but is starting to clear up a lot.
