Did my Aeroforce Gauge now
 

Wow what a difference, GM should have their heads examined there is nothing to compare between the Turbo Boost gauge and the Aeroforce Gauge. The top is the H/P and the bottom is Turbo Boost. There are 24+ settings on this gauge so get yourself one as well. It bolts right in and plugs in. Had it done in 4 minutes. start to finish.

That's pretty cool, where and how much. :) How do you get the stock gauge out?

Ditto, I know ADM has em.... how is the install?

The install was a breeze. 1 bolt under the airbag sign. use a small screwdriver to remove that then undo the bolt 7mm. then pull on A-piilar in pulls right off. then unplug the 2 plugs 1's for the gauge the other is the Tweeter. undo the 2 nuts off the back of the gauge it slides right out of the hole. The gauge in return goes right into place. then run the 5' wire down and plug it in reverse the steps your finished. It was that easy. I got mine from Stylin Concepts I used their discount of I believe it was 20% at the time. but here are others that you can order from right off their site: All I can say is WOW what a difference between the 2.

Horsepower at the top? How does it do that?

It puts it upon throttle responce. It's actually pretty cool gauge I highly recommend it.

Thats sweet! definately something to look into, is there a different link, the one you posted isnt working for me...:one:

How accurate is the HP reading? Has it been compared to a dyno? Does it measure engine hp or calculate wheel hp?

We sell a ton of them.

I will work on a coupon for hhr ss guys...Sound good?
