KA KA24DE horrible run

See, i have this stock KA24DE that recently i overheated it, all gaskets where replaced and it was running good. I bought a daughterboard with a flash and now its throwing me code 34... after 10 miles, it had a little improvement but still was slow as crap. The car when i press full gas it won't rev up and backfire a lot, when i press little in the gas, it will rev up but not fast... it seems up from 4k rpm its not that bad, still its bad. i think its running too rich but how could i fix this, ecu wont adapt, or i HAVE to do something about 20 miles or more and this is normal when you flash it... please help! its tuned for full stock ka


thanks!!

its like i press gas strong, then leave it and it will rev up, then it will go too 400 rpm and then to normal idle, sometimes it wants to stall out
