Hey all,

I have not been around this forum for a while. I have a 2003 C32 with the following mods:
57k miles
All maintanance up to date
Eurocharged SC pulley/tune
Resonator delete
SL55/K&N intakes and filters
ECU DIY reset
I am curious how much more HP I can gain without throwing a ton of money at the car. I would assume that I am currently about 400/+ at the crank? I also have NGK Iridium to install. Is there any logic to replacing wires at this mileage? The car is quick, just looking to get the most out of it. I am working on a build thread as well, should have it up soon. TIA, Mike.

Maybe remove the secondaries if you want to keep it on the cheap. I'm in California and I did it without worry of the emissions repercussions + the sound is great.

You can get a intercooler reservoir and split the cooling system pretty cheap, should give some good hps on hot days..

The cheapest would be to delete the secondary cats...sounds better too but doesn't gain much in HP. You really needs headers/collectors to get a big gain but again that's big $$$.

Bigger HE/coolant split would really help keep intake temps down but that's going to be at least $400 in parts alone.

no power gains on c32 by deleting secondary cats unless you have headers and higher flowing primaries....and even then, gains are minimal

deleting secondaries are purely for sound. do you want it louder or not? that is all
