i think in ISB short ram is perfectly fine but here in Khi its opposite, recently my car got reflash and i had unichip as well but the knocking was going worse so i went for reflash as it has eliminate the knocking. From unichip i gained around 21whp but then iat increased which lead to timing pull/knocking. The best thing is to reduce IAT is from bigger volume intercooler, also i noticed the engine bay get too hot as there's no proper ventilation to cool down the engine or turbo. Btw there's no complain of injen cold air intake in rainy area in US.
