Best Performance Mods for Colorado

[CslRkH2]

I just bought an H2 and am curious as to what anyone from Colorado (due to altitude considerations) would recommend for performance enhancements. Looking for the biggest gains for the buck without going the S/C route. Any suggestions would be helpful.

Thanks

Hypertech programmer and Catback exhaust.

Thanks for the response.

You would do the catback before an air intake?

I put a flowmaster on a Sierra and didn't notice all that much of a difference other than the sound.

I would go with a Volant kit for the air box and than the new MAF sensor and tube. Than the exhaust. But first, go buy a hypertech programmer. I think you will notice the diff. and be happier with that. I can PM you the settings that I use once you get your Programmer. Just let me know.
Good luck,
Tim.
