In January i'm going with TSP CATTED headers, holly sniper, pmas cai, and Lund ff tune. How much of a hp / torque increase should I expect over stock? How much of that power will I lose if I fill up with 93 instead of ff? One last question, how much power am I missing our of by going CATTED over catless?

Depends on the dyno but normally most will go from around 380whp to about 455-460whp with those mods on E-85. Roughly 80whp gains which is close to 100 crank hp gains.

Newer high flow cats are mostly negligible in my opinion. I thought I read the true E85 Vs 93 is good for about 10-15whp with FBO.
