Why do some people get more hp with less mods? Like a have Cobb catless dp invidia q300 exhaust cnt el headers gs 3 port boost controller Cobb Ap Cobb sf intake 1050x injectors 320 fuel pump and only got 295 hp and I have buddies that have less mods with 305 hp.. it’s frustrating.. just bought a delicious flex fuel kit that came with a stumble fix and a Process West TMIC and am going back for a flex fuel tune on the 14th of this month and am hoping to get at least 350 hp is that far fetched or should I be getting over 350?

The thing you are failing to recognize is that every single dyno reads differently. Some shops will even calibrate their dynos to read a little higher to satisfy the customers that just want to see the number. The chances of your car actually making 295whp is slim. The only true way to know how much hp you gained before mods is having a base tune done and see the difference in hp was before you added them all.

But there are also many different variables that can alter dyno readings. Such as altitude.
