Recommendation for GIAC Dealer

[Adam]

He said he lost hp everywhere except at the extreme highend of the rpm range which is probabbly not uncommon. I wouldn't be suprised if EVO is being a bit optimistic(like most aftermarket parts companies) about an 8hp gain and even then that would only at be at very high rpm.

This would be true for something like a muffler. But for an intake to show gains up top (which means that it is working) and losses down below is suspect. It either flows more air or it doesn't. I really think the a/f mixture is out of whack and the computer needs to readjust.

Clubhead,
I'm really surprised by Evolution ignored your emails. They seemed very helpful when I ordered stuff from them.

Regardless, try contacting Dynospot Racing in San Jose, CA. They might be able to help. http://www.dynospotracing.com/

BTW, isn't Australia closer than the US? Don't they have GIAC dealers?

Many people have baught the evo and proclaimed how happy they were. Now it is manufactured differently to not send a cel. I called them today and was happy with the info I got. Seems like it should not lose power like that. I would have to agree that the mix is off. Sounds like a bad MAF to me. I heard of another guy that lossed like 10 h.p. with an scargo intake on the dyno and I think it was due to maf problems as well. Maybe you got some oil on it.
