Well for my stock standard t besides the show off valve on her I got 193.8 rwkw I was happy with the outcome and now I know a few minor cheap mods I can do to increase the power. And as for the car that got approx 213rwkw didnt it have an cold air induction system on it and different exhaust setup, which gives it more power. Just curious to know cause it varied a fair amount from the actual stock standard cars!!! Im still learning alot here about cars and just curious on feed back thanks Jen
