2003 Buick Lesabre 3800 V6…How Can I Economically Increase Horsepower From 205 Up To 240

Obviously, demand is low for mods on “grandpa’s Buick” but it is a well built semi luxury vehicle. Just want to give it a little more muscle, reminiscent of that back-in-the-day GM performance we younger guys kinda missed out on. I want the power of a v8, from a large six cylinder that gets surprisingly good fuel mileage.

I’ve read about performance programmers and chips, as well as cold air intakes and exhaust, but haven’t been able to find many after market parts available. I’ve spent hours just looking for a programmer, as I’m thinking that would be the best choice.

What can I do for under five hundred to start?
