That's where a good tuner comes in, and the reason why a less experienced owner shouldn't jump into bumping up the power without doing their research. Someone who has done the research, and knows what they are doing can do it, which includes selecting the right tuner. But the reason I say they should build the motor is, even if you are bringing in the torque much later in the rpm range, there is still additional stress being put on the pistons and rods, which may shorten the longevity of the engine in the long run. But we don't know if that is true or not until someone has done it at least 100K and disassembled the engineI disagree strongly with building the motor after 250whp. Many people are running bigger turbo setups where the torque comes in much later and that seems to be the difference maker. The stock turbo on E has 350lb ft of torque hitting around ~3000rpms which is crazy for a tiny motor. That’s where these motors get stressed.
Shift the power curve to the right and these motors will be much better. It’s still a small motor so you’re definitely limited but saying the motor should be built after 250whp is silly. Look at MAPerformance and how long their stock motors have lasted making big power. Their powerband is way higher in the rev range obviously and it worked for them. I believe at one point they were running over 40psi through the stock motor.
