Thoughts on power adding harnesses?

If it's the one with the dial on it to trick the fuel pressure sensor so the engine sends more fuel. It's COMPLETE BULL$HIT, it'll do more harm then good! I've used one on my cm870 before I joined this forum and all it did was blow smoke, literally... and permanently cook the injectors.. Proper tuning is always the best path instead of ugly fixes that only cause destruction in the short term...
