Re: help choosing tc
Stock is 2050 - 2100.
A looser stall will mean that you end up overboosting the turbo earlier on so it will pull timing and buck and not be much fun unless you make your wastegate compensate.
It's similar to the effects of removing the catalytic converter - you'll have the boost come on more quickly but it will be ineffective due to the looser TC.
As for launches, it'll spool higher than normal and when you floor it on the street, it'll spool very high but you might find that the response is slower.
