Mine is also a DD and with a good tune it runs great. It only has 2k on it since install so I cant say what will happen long term. If you don't get stuck on hp numbers the kit is definitely an improvement over stock.

DD??

I don't think it's cool that you guys are bashing the stillen kit. As long as the kit is reliable, built well and produces the horsepower that they claim it will then its cool. You guys are also upgrading your GTM kits to get a helluva lot more horsepower. Most of you aren't running standard GTM kits. I don't understand what parts of the stillin kit are not good parts; meaning they would need to be replaced and not just upgraded.

thanks :)

:confused:

Boosted Performance explained exactly what parts need to be replaced.

So let me rephrase my question. I'm looking to get the most out of the kit possible without doing any upgrades as of yet. So again I ask what parts are not good? To get the 400 plus horsepower that stillin states and to have a reliable car what parts need to be replaced. Boostperformance is suggesting to replace those parts to get much more than the quoted horsepower by stillin.

thanks :)

To try to keep this from boiling over.
People are not saying the Stillen kit is bad, just that it lacks certain aspects that the GTM kit is better at. Some of which people like, such as growth potential, TQ, cleaner designer, and I am sure there are some other points.

You're initial post came off a bit harsh, you wanted to put the all Stillen bashers to rest. Yes, we are all looking for people to be innovative and creative to achieve a new level on something, but do it with some respect to others. Many have tried to improve on the Stillen kit and have done fairly well but at the same time others have found the wall and realized it was not worth it to continue.

If you want it to be reliable, get a custom tune and keep everything cool. Oil cooler, radiator, bigger heat exchanger for the intercooler. Maybe meth. You're in a hot climate. Dont go chasing a hp number.

A bigger radiator?

thanks :)

I haven't seen anyone modify a GTM kit.....

dreamer said it best. That's the best way to go about it.

A bigger radiator, an oil cooler and a bigger intercooler/heat exchanger would be very helpful in keeping temps down. Maybe upgraded radiator fans. Meth injection would help keep the intake charge cool. Maybe look into a vented hood. You're in a hot climate, these cars run hot anyway, and boosting a car adds heat.
