Those numbers are not too helpful without air fuel curves. Any gains could have simply come from them leaning out the A/F curve. I know they "claim" it was kept the same, but I like proof. Yes, I am skeptical of this product on 96-98 cars. A couple HP, maybe. 7-10hp, doubtful.
Plus, they are recording gains for parts of the graph where the TC wasn't even locked up. 15 ft #'s gain, lol. How many stock, auto, NPI 4.6's lay down 320+ ft lbs to the wheels at less then 2000rpm. That alone shows me that they are trying to pull a fast one over on customers.
