Hey,
I got my VP Calais (Buick 3800) tuned for the second time but got less power than the first time I tuned it with more mods?! SO:
For tune No. #1:
Wade 992a Cam, 1.8 YT High Rollers, Mahle Pistons, 2.5k Converter, Lukey Extractors + High Flow Cats + 2 1/2' Exhaust, Custom Rods, 40thou Oversized Rings, 10:1 Comp, Machined and Bored. Stage 2 Shift Kitted Auto - 4L60.
Power: 142rwkw @ 407nm Torque.
For tune No. #2:
Added Twin Throttle Body & 2x Brand New K&N Pods, Bosch Blue Top 775 Injectors 24lb & Freshened Up Motor a Little.
Power: 129rwkw @ 680nm Torque.
Has something gone wrong or is one of my mods robbing me of power. Can't work it out?
EDIT: After the second tune, it sounds a lot more 'droning' on low revs compared to the first one. Pulls very similar though.
