I agree with everyone on here. I'm not sure how much more HP your ecu can adjust to, but I'm sure your not making it yet. I would only recommend spending the money if you are planning FI, nitrous, internal work, ect. I believe most stock injectors are only at 70% duty cycle and can be run up to 90% safely so you are good up to roughly 20% more power. Don't hold me to that, but I'm pretty sure its right. As for venom400, its a great paperweight. As for any kind of performance enhancer, POS. Some people actually don't push the pedal to the floor, so this kinda helps them out. Its the equivalent of putting a 1" thick block on your gas pedal. I can't believe they charge $300 for that thing. Highway robbery.
