Need a little help When tuning a car to light the turbo off while on the transbrake and 2step I have read many threads in which to run as much timing as possible to get the turbo lit and then feather it out after leaving. I have logged many times and adjusted timing in the base table going from 18 degrees of timing all the way to 39 degrees of timing and it seems the turbo will only build 4 lbs of boost in 5 seconds. turbo is a tc78 Benita series with the 68 mm turbine in 96 a.r. I would think it spool like a light switch. I have also adjusted the PE to table to command . 84 lambda at the specific rpm while on the transbrake. Method for attempting to build boost while testing is to come off idle, hit t brake stab throttle, come up on converter and 2 step and hold it there for 5-6 seconds for testing purposing then release throttle and brake button. Doing this is in the dirt for testing so I don't break anything. Is this the appropriate method and way to accomplish lighting the turbo off on the brake and adjusting the tables in hp tuners. Thanks for the help and sorry for the long read. Here is a copy of the tune and a log
