Thanks, Granatelli for taking the time to explain the issues and deal with the bad press and for some, their poor product results. As far as I am concerned you have offered to do everything you could possibly do to resolve the issues, namely to offer to fix the problem. That's all you can do and it is a lot more than I have seen other manufacturers do.
I have been considering trying out your product and am going to do so because your posts have impressed me. I have a bone stock Z06 and would love to bolt something on that has the potential of 10-15 hp, especially knowing that if it doesn't work I can have it fixed or return it.
I also want to say that I don't understand the mean spirited posts from a couple of you forum members. Doesn't appear to me that you want to be helped...just to complain. When someone is kind enough to give us their time and attention and try to sincerely address any negative issues they at least deserve common courtesy...not someone continuing to bitch
about the very thing they just offered to fix. I don't get that one at all!

completely!Mr. Granatelli....You do have to be complemented on taking all this BS and hanging in there. Hat's off to you. Really.
My personal experience is I have all your intake stuff from the Halltec air intake, MAF, carbon fiber bridge, MAS, etc. right up to the Z06 manifold and my results have been very good. No codes, no troubles, nothing but a noticable increase in "seat of the pants" acceleration. Sorry, nothing high tech here. As I'm just getting a heads/cam set-up installed now and will be followed by a dyno tune next week, I hope I can continue to have these as part of my upgrade list as not only have they impressed me personally (as have you), but they look good doing it! I forsee no issues arising, but thanks much, in advance, for the offer to help if needed.
Best to you and your company. Thanks again for taking time out of your, I'm sure, busy schedule. To hang in here without it degrading into name calling and petty insults is admirable. Not sure I could do it. Very iimpressive, indeed.
Take care.

recieved it
I just recieved my GMAS back from Grannatelli. I will install it tomorrow and take it out for a couple of WOT runs through a qtr mile or so. Then I am going to a drive to see if my engine light comes on, this is primarily the problem I was having. Will post to let Mr. G know how it went. Thanks Mr. G for the prompt service I will keep you posted.

works here
this is a great thread, caught it as I was about to intall the new G MAF C on my 02 Z and the air bridge and G twin filter air intake. Took about an hour and the "test" drive went great NO CODES...no problems and you could feel the difference. The Z is stock except for the above and a coolant bypass and the new hurst shifter the wife and I put in this weekend. It is assuring to see Mr. G stand behind his product and take care of all the problems people seem to be having....way to go.. I know who to purchase things from in the future !!
