A somewhat local place had a surprise dyno day so I went to try and tune my car a bit. Was somewhat successful, reaching 405 HP and 420 Ft-lbs. before giving up. I was hoping for 450 HP, as my turbo and injectors should be able to support it easily, but oh well. I couldn’t get past ~14psi or so.
But I kept experiencing some spark blow-out and had a rear main leak, so I decided to cut it short.
