Dyno'd and Tuned at/by Big 3 Racing in Hinckley, OH.
Muffler delete+dyno tune= 269rwhp/285rwtq (292/309 after weather correction)
Car feels better, problem is...it gets much hotter with 22psi vs at 14psi, so it pulls timing and the car becomes as slow as it was stock.
Time to buy some cooling mods and keep the intake temps low!
