I have an 07 magnum sxt with the 3.5L high Output I just purchased, Trying to make some performance mods and get the most out of my magnum. I know I want to chip it or flash it. Dont know much about cars so any help anyone could give me would be greatly appreciated on what I could do. Also would like some input on chips like trustable brands etc. Thanks

 

i would buy the diablosports predator for this car. with it, you can adjust most fuel and timing parameters. there are some preset custom tune built in it too. i would also get a 180* thermostat and adjust the fan setting to keep the motor around 185*. this really makes a difference. the predator has some trans settings to improve the shifts and drivability. you anc even correct the speedometer for different size tires. well worth the $399 list price. this is a must have for anyone looking for more.

 

buy one with a hemi.
