What more to add?

Chinajohnny · 09-27-2007, 08:44 PM

I have the 5.7L 300c Hemi.
I installed :
Magna flow exhausts
Airaid cold air filter
Throttle spacer
Jet Chip Stage 1 , i believe.

What things can / should I add to further improve the performance ?
Something that still REALLY makes a difference.
I thought about these tuners but they are so expensive.
You use it and after that it becomes useless!
There should be somebody starting a little business , visit 300c owner and to the tuning for $100.
Does for example this Superchip programmer still make a lot of difference when you got the JET chip installed already??
Maybe one of you guys wants to sell their programmer ...................
Love to hear your advice.

PORTED AND POLISHED HEADS, LONG TUBE HEADERS, PERFROMANCE CAM, b & G FLASH- ALL IN WORTH ABOUT 80-100 HP AT THE WHEELS.!!!

You have any experencie with these computer upgrades?
Like super chips ?

superchips is more about modifying the driveability charcteristics than about increasing the HP. No big gains, just a little tweak here and there.

Diablo promises to be better, I'm still watching and listening for results.

You should listen to SRT8/BMW, his car really hauls ass and is a legitimate SRT eater!

The superchips is a good way to firm up your shifts and raise your idle. It doesn't really add HP, but it does seem to "extract" existing HP from the engine to the wheels.

The B&G flash is even better because it does that and seems to add HP you can feel. The Diablo, which was just released, is supoesed to be even better in that it can be somewhat customized to your cars mods.

Yes..if you add headers, it does make your car louder...but with the cam and polished heas, now your engine will really be able to breath the way it wants to, and it will have power you never even knew was there.

I race my 300C against my srt8 (stock) and it consistently gets it off the line or from a roll. The power in the low rpms is superior in the 300C....the srt8 tends to catch up eventually, but its not until you get to around 110 mph.

here is a sound clip if your interested...
