Hello.
I upgraded ICs and I'm wondering if there are actually any benefits to retuning after the upgrade. We are, after all, on an SD platform, so it seems like any changes to airflow and temperature will be accounted for by the ECU anyway.
A return seems like a waste of money.
Thoughts?
Thank you.
IDK if power delivery and trans shifting could be re-optimized. Certainly, the ECU is seeing everything it needs to, like you said. And it's not like you have changed fueling, like if you had meth injection installed (cooling + octane).
There are a couple of things that could be changed regarding IC volume and transient fueling but I wouldn't worry about it....Hell, there are Meth tunes with no changes to the fueling.
I would say your average email tune wouldn't make changes for an IC upgrade
