LSvtec turbo Cold start wont stay idle :(

hey guys , i have lsvtec turbo , with forged internals and aftermarket everything (sk2 pro1 cams , elderbrock manifold with sk2 70mm TB, t4 turbo , 1000cc ID injectors , AEM rail and regulator ) in the morning i have to hold the gas like 30% and let it runs for a min before i can let go of the pedal and let it warm up , i have tried stock base for starting fuel and same thing , before i had b16 turbo with b16 manifold it was starting ok with almost stock FUEL setup .


any ideas how can i fix it ?

i changed the fuel based on intake temp sensore and engine temp but still the same , it starts and runs good when warm just first in the morning is like old cars you have to give it lots of gas :D

i,m not sure if it needs more or less , i will upload the calibration

thanks

Has this been properly tuned on the dyno?

If you have a problem, your car does not stay in idle mode! is that referring to? it is very normal that you have that problem .... but if the mechanics do not fail (no vacuum hose and everything is in order go to the fuel maps) it will take 1 min to correct that problem .... it is very simple friend
