What do you guy's think of the Jet computer upgrade

[Sinner]

I was wondering if anyone else on here actually has the chip I bought it awhile back and noticed a little bit of a lack in bottom end power but a definte pull on mid to top end. I also hear A lot of people bashing it but none of these guys have it on there cars or have ever had one for that matter. my question basically is what was your expirence that you had after adding this to your car?

Worthless.

edit: After reading your post I realized I don't personally have experience with it but everyone I know that got one said it did nothing.

i sent my CPU to jet and when it came back i realized that i paid about $400 to ship my ECU to cali and back. when i eventualy got my AFC i also realized that they basically set my ECU to dump insane amounts of fuel into the car beause with 660's and a green turbo, i had my settings around -45% across the board. i called JET and asked them if they could explain anything they did and their responses were about as helpful as talking to my three year old neice about my car. at least when i talk to my neice i smile cause she's adorable, but jet just gave my copout after copout after copout. i would highly advise not doing business with JET. they suck balls

Now I guess I would say mine was a positive upgrade not worth the amount of money I spent thou cause even thou I lost some bottom end power I did gain a noticable difference in the mid to top end range, but I got this upgrade done about 7 months ago and I have been living in Wyoming since then the altitude here is like 7200ft. so in a few weeks I will know how it does at sea level when I graduate Wyotech and go back to New York I imagine the lack of air up here messes with the fact that JET make you dump a lot more fuel into your engine.
