It's because I keep changing setups. 3 engines, 3 different super chargers, custom inter cooler system that uses the A/C to keep IAT2's down. 4 different sets of tires and rims. Also changed suspension a few times. I can never just leave it alone. I get bored, rip it apart and start new. It actually is closer to 1000HP now since I have a 150 shot of nitrous io it. The 800HP dyno was without the nitrous. Oh and I added a few new vinyl stickers, so that's gotta be good for another 50Hp at least.
