what is the greatest achievements you did on your car.

Nice work you get an A+ from me.
Thanks. But I'm fighting with timing more. (I'm sure it's the fuel difference.) E-85 wants more advanced timing. (Especially at idle) But getting some popping at the top end. I know MANY have seen this. Especially as builds increase in power. But still struggling to find the sweet spot. I'm wondering if I should have set valve timing more advanced? I may try MSD module that's supposed to be able to take a little timing out as RPM increases. (It won't turn ones setup to a variable timing. But this delay module is said to help?)
