[QUOTE="pholmann, post: 466185, member: 5330"] I will give you a serious answer on this. There are many variables that make a huge difference. First, on a stock motor, your not going to gain more than 15-20 at best. With an aftermarket cam or a good head swap (ls2/6 heads, or l33 heads) your going to need to tune it. This is where a custom tune comes into play. Buying a generic "hot tune" wont cut it. Its like buying a one size fits all pair of jeans. It just doesn't work. There are a lot of things that will depend on how much timing is put into the engine, fuel curve, etc by the components you have installed. The cam is one of the biggest factors. A good cam and custom tune will get you to 50 or so. The best thing to do is have it dyno tuned. That way the tuner can see in real time exactly what is happening with the data and manipulate it for the best performance possible. Stay away from generic tunes. [/QUOTE]
