Need help with lt10s base map (car dies above idle)

I finally got my lt10s fixed from microtech to run my 13b cosmo engine. The car starts and runs, my innovative wideband reads about 11.9 to 12.3 air to fuel ratio. But when I rev or give the engine some gas, it completely dies. I did try to change some values but that may niot have helped. Anyone have an idea of what value to change to get the car to not die above idle? (my idle is around 1500 ish) thanks!

I am running stock setup for the most part. Stock twins, bosch coils, no intercooler for now, stock fuel pump, v8 radiator, fuel pressure regulator to 43 lbs I believe, stock injectors, k&n air filter, running 2 stroke premix without omp, custom pressure pipe (same size as the port size coming from turbos can't remember size off the top of my head), and a custom exhaust same size as port size, Something like 2.5 inch I believe. Do you have a map to suit this? I just need it to run to break in and then to a tuner later on.

I think I know what your problem is. If the engine dies when you give it gas or rev it, run a compression check. It sounds like one of your rotors and seals are bad. Don't waste any more money until you can verify both rotors and seals are good.
If the rotors are bad, you would have to replace your housing as well.

That is just a chance you take when you buy a J-spec or Cosmo engine.

if motor starts Ok hot and cold then its fine
if it dies when you rev it then almost certainly the TPS is not calibrated and or the throttle pump settings are incorrect
