For those of you who have a grainger value on your 1st gen GT, are you happy with it? Do you think it is a good cheap alternative to a HKS EVC?

I have one and I love it! I had it cracked to what I think was about 13 psi and I blew away my friends 1990 RX-7!
Lot's of fun!
No drawbacks that I can think of save re-fueling more often because I'm always on the gas now...

I have one as well. I can't think of a cheaper, better value/dollar boost controller than a grainger valve. I spent under $10 and got a valve which was much more effective (and stable) than a bleeder-type valve. I highly recommend it!

Check out this well-written site for grainger valve installation: http://pages.cthome.net/gus/mike.html
