Couldnt pass this up!

Thanks!! I was kinda having buyers remorse for just buying it without researching them, but I know my dad put a lot of time and money in the front end, us three in a bunch of new parts he didn't have time to install. He's a retired mechanic, so he's always tinkering with stuff til he gets bored, then sells it to make room for something else. Any ideas on simple bolt ins to add a little more snort to the hem is? I'm putting the exhaust and cold air intake on today. Considering a diablosport programmer but I don't have any experience with this late model stuff
