Default my car is running pretty rough on the AFC hack

when i get on the gas and let it go, it is really rough.
when i rev up the engine and the rpms drop back down they fluctuate...
any ideas on these problems?

... add more fuel at idle... try -25%... you need to do this to compensate for the longer opening time of the larger injectors...

Do none of u guys have trouble with the car real overfuelling on COLD start??? i have to have mine set to -25% to get it to idle smooth, its fine once warmed up but on cold start its overfuelling and misses due to the huge excess fuell!!! its really annoying, i have to adjust the afc before i do cold starts!!!! surely this aint right
