Hi guys
I'm running an EVO4 STI with the 2611 pipe on my NT1 and I'm having a small problem with run time.
I cant get more than 3,5 minutes out of a tank.

The engine runs at around 120 celsius.
I'm using Tornado 16%.
Also I changed the carb for the EVO3 STI as with the stock one the engine was untunable.
