I was watching a few of the Horse Power TV marathon episodes today and they had a 98 LS1 Camaro on there. The first episode they did a new throttle body and SLP ram air lid. I think they may have done a cat back also but not sure. So the baseline dyno # was 300whp, I can believe that. After the mods the hp jumped to 319, ok so that seems believable. Here is were it seems shady, The next episode with the Camaro they did another baseline run and only came up with 306, where did 13hp go? So after that they added headers and tune and came up with 334hp. I think Horse Power TV may be manipulating numbers to help sell the advertisers products, what do you think.
