Yotawerx just released dyno charts on their tune for Doug Thorley LT headers;
Stock 2UZ; 216 HP / 250 TQ
+DTH/Y-Pipe; 226 HP / 265 TQ (+10 HP, +15 TQ)
+DTH/Y-pipe/LT Tune; 249 HP / 297 TQ (+33 HP, +47 TQ)
Impressive numbers I can only verify via butt dyno, as I have this setup. Drives like a completely different vehicle. Feels like I dropped in a 5.7.
Calculated power loss vs factory specs;
216 HP (wheel) / 263 HP (factory at crank) = 82%
250 TW (wheel) / 323 TQ (factory at crank) = 77%
Theoretical back-calculated crank HP with tune/headers;
249 HP / 0.82 = 303 HP
297 TQ / 0.77 = 385 TQ
