Sounds like you had your traction control button on. That happend to me once when I have N20 and left my traction on it shut down my whole car and lite up every light. Turned the car back on and it ran normal. Just make sure you remember to turn the traction control button off. This happens cause the car is getting MUCH more torque than it is supposed to understand.

Check the codes and see if you are getting a 1514

Your car needs tuning. Who tuned it after you installed your blower (please tell me it's been tuned )

You need to adjust those parameters. You need to tune it so it does that under more extreme conditions. Do you have any way of knowing what your Air/Fuel ratio is?

My 99 MN6 did the same thing before Ed Wright tuned it. It dynoed 477RWHP with no other mods. He does mail order tunes as well.

Put your baby on a dyno and dyno tune it. Mail order can get you in the ballpark but if you just dropped a bunch of money on a blower, do it right and get a custom tune. Every car is different, and you don't want to risk blowing your motor.

Purchase scanning software and run traces on your car while you drive. This is how some people can tune a car... I know its a lot to have to learn. but in your situation, it may be the only way to do it right.

This is Ed Wright he is the only person I know of that can mail order tune your PCM and get it in the real close, the only problem with using him is he locks the PCM so you can't make any adjustments

Yep - this is the way to go - as you drive the car, you monitor its parameters, and make adjustments until it runs the way you wish. Done right, it is better than dyno tuning! Immerse yourself, learn alot - hey, maybe you can start up a business in your part of the world!

Well I think the topic's been covered well.
I'd just like to add that the tune is the most important part of the install. Bar None.
For anyone else reading this deciding about a SC for their car, if you can't afford a dyno tune by a top rated tuner when everything is complete, don't do it until you can. That is, unless you can afford a new engine. Just my $0.02
Broken belts and pulleys are cheap to replace but a blown engine is a whole other level of maintenance.
