Hey fella. First I want t say thank you for this mod, thats what I've been looking for AC.
I had a chance to drive 2jzgte car in real life. Your sound mod sound very similiar to one I drove.
But have some note. In AC it sounds good but I can't feel engine torque. The sound loop what begin in 5,5-6k rpm share it till 3.5k rpm and higher with minor fixes. It will be best mod of 2JZ GTE in AC in my opinion :)
P.S I did learn a bit FMod. But have no time and skills to make good samples(loops).
i think i have to reduce the sound of the blowoff first because if i make the sound too loud we didn't hear anymore the other cars.
