$1500 ECM unlock plus $500 in credits plus a spare ECM (in my case anyhow lol) Still crazy that it's happening!!

I’ve tinkered with a few factory-locked setups before, and having proper access makes a huge difference. I used BMW E90 318i Chiptuning https://www.gantuning.de/chiptuning/bmw/3-series-e90-2005-12/318i-143hp/ on my daily, and the smooth install and reversible setup took the stress out of trying things. If HP Tuners keeps the process just as clean for the Z06 and ZR1, dialing in small tweaks without committing long term should feel pretty comfortable.
