I'll see what I can do. Bill, have you thought about being an Event Sponsor for the C.P. Meet? Hook a brother up :D :p:

60 WHP is a very nice gain! BUT...
Is there any concern that it would turn the HHR SS into a torque-steer demon?

It's a valid concern, but mega-powerful FWD's are something we are very accustomed to here at Hahn RaceCraft! We just hang on and enjoy the challenge...:eek:

All kidding aside, today's FWD cars are much better suited to this than their predecessors. Refinements in suspension and driveline design have significantly minimized the torque-steer effect. We can rely on the HHR/SS to have had these refinements in mind from the onset of its design, and as such, it's not going to be an issue.

boy would I love to be the first guinea pig to find out!
Unfortunately, I don't own an HHR SS yet, but hope to soon...
I'll just have to keep driving my 98 Z28, which hauls bazooty but doesn't get very good mileage.
BTW how does your reflash affect fuel economy?

Fuel economy is not affected, so long as you can resist the urge to keep your foot in it all the time! :D

What is the effect of the tune on the warranty?

Are you willing to touch the HHR SS with the slush box?

Once you have the development done, what is involved with installing on a new HHR SS? Will you send out a unit and have the person swap ECMs (send back the old)?
Will it be a module that you plug in and reprogram it? How many cars can it work on? What are we talking as far as price? Do we need to do other hardware upgrades to suit the car better (you mentioned intercooler)?
And what about Kizzme's question about the warrenty?

:confused:

Enquiring minds want to know...:D
Thanks

A very good question.

If you are concerned about warranty coverage, you should not modify your car. GM's obligation does not extend past the stock power level. If they are aware you are increasing the power level, they may well void your powertrain warranty.

The Magnuson-Moss act specifically defines how your rights as a consumer work in such cases. The manufacturer cannot void your warranty on items unrelated to the modifications you choose to perform. If you want to learn more, look this act up on the Net...it's a bit dry, but it spells it all out.
