So people on e90post are drooling over the numbers made on stock hardware. The numbers are impressive but they are running 18 psi which to me seems very aggressive on stock hardware. Of course we would need to see logs to determine how the car is reacting to it but it seems to me that there is a reason that the other tunes are hitting much less boost with stock hardware.
I have pointed this out on e90post but of course Shiv defended his tune and indirectly bashed Cobb for having a conservative OTS tune.

| Our OTS tune runs 18psi briefly right around 4000rpm (see below). Which means just for a second at a time when WOT on the road. Turbo is efficient at that rpm/airflow and intake temps are low. Much above and below that engine speed, its in the 13-14psi range. At 6700rpm, its down to 12psi Definitely seems to be a few who are making excuses for underperforming tunes. Perhaps their efforts should be on making their tune work better and not on suggesting a well performing tune is unsafe and should be brought down to their level for some perceived safety reason. I encourage those who believe this to drive both tunes. The biggest difference, IMHO, is not even power. But rather drivability and response to throttle (immediate and consistent vs delayed and irregular). There is a reason for this and if people can focus on things constructively instead of destructively, perhaps it will benefit them and the community as a whole |
