So I pretty much don't know how much horsepower my car has. All the aftermarket parts are listed in my signature, how much do you guys think I have?

 

Get it dyno'd. Guesses mean nothing and you really don't have a lot of power adders.

 

^^ What he said.

 

if i had to get guess, maybe somewhere around 290-300hp.

 

I agree, you'll probably be around 290-300 RWHP, but the only things that you have right now that are going to help you out are the headers and the intake. If you don't have an aftermarket Y-pipe on it you're probably not even getting too much out of your headers. Make sure you have a full mandrel bent exhaust and with all the other mods you do have (most of which the car doesn't need right now, such as bigger injectors/TB) you're ready to put on some new heads and a bigger cam and make some real power.

 

As these guys said, dyno tune. Imo, atleast get a mail order tune since you got bigger injectors.
