I've been thinking about doing a chip. But $1000 is a bit steep. If I did do it I would dyno the car before the chip was installed and after and see if it actually did anything. I would not be pleased if it did not give me at least 10 hp. $100.00 per HP.

I hear you... 1k is a bit steep but if it does what they say it should be alright, and the other one for 250.00 I really can't trust them. but I'm going to LA in about 2 weeks I'll go check them out. Thanks but if you know any info please drop a line...
