that turbo should be hitting 14 - 17 PSI by 3500ish

you need to set START to around 7-9PSI. that prevents the wastegate receiving any boost feed until that threshold is reached which will make it spool quicker.

Stock ECU mate.

Don't anymore than 12psi right now until I get it tuned.

I will play around with the start though. See If I can get a little more response.

Its hard when you are by yourself though. Trying to look at your boost guage and monitor everything without smashing your car is kinda tricky lmao jk.

I'm in a very similar situation, Greddy Profec with stock turbo & ECU.
I have mine in control mode, currently running 25% SET, 5psi START & 0% GAIN.
It spools up hard to 5psi even under fairly low throttle percentage, then holds there.
Then under full throttle it continues to spool up to about 10psi.
This should be safe enough until the car gets tuned.
PS- may I suggest late night 4th gear highway pulls... :rolleyes:

get a Nistune, pull some timing back

stock JDM ECU has too much timing in the mid range and you'll easily grenade a motor with too muhc boost and high IATs
