Question What should be my next engine mod?

Here is a list of mods I already have.

Gutted CAT with high performace exhaust.
After market fuel injectors pushing around 60 psi of fuel pressure.
The chip has been reprogramed.
The timing has been changed.
After market spark plugs.
Drop in after market K&N.
After market MAF.

Next one for sure is going to be an K&N intake but what after that?

If you got an auto, I'd get a tranny cooler, there fairly cheap, and are good insurence, and easy to install too.

What programming do you have? Why do you have aftermarket fuel injectors? Why do you have such high fuel pressure?

I'd recommend removing all of that crap and starting from the point where you have just the gutted cat and exhaust. Then do a cold air setup like the K&N FPIK.

Yeah I have an auto. What does the tranny cooler do? Just keep the conveter cool?

What do you mean by high performance exhaust? For me, high performance was FULL exhaust, not just cat back....what is your exhaust and your budget?

i agree with the other guy...what is with that high of fuel pressure??

if you are lookin for simple bolt ons you could go for pullies, air foil (almost useless) and maybe an electric water pump...

if you want something bigger...get headers or a higher stall with a cooler and shift kit

Well guys I brought this car used and really I do not know what is really what. How could I tell if it is cat back or full exhaust? Also I really have no clue why the fuel pressure is so high, I just know that is why the guy told me. You can tell they are after market injectors but I need to find a way to check the pressure to make sure it is not set to high.

Since you already have upgraded your injectors, why not run nitrous? Is it possible the guy before you was runninga dry kit and that's why he upgraded the injectors?
