Granatelli Turbo Install - The Final Outcome!
For those of you who were following the first few threads about my turbo install, you know I was having some issues. Ultimately, it turned out to be a problem with the tune not opening up the Charge Motion Plates.
A new tune was emailed to me immediately and I finally was able to meet up again with the tuner this morning for a final tweak and some dyno pulls.
First Pull: Only some minor tweaking to the tune:
434.8 RWHP, 464.1 RWTQ, 6.9 psi, 11.7-11.8 A/F Ratio
Second Pull: One turn on the Boost Controller & some fuel added between 3500 and 4000 RPM to soften the rise in the A/F ratio:
475.2 RWHP, 505.6 RWTQ, 10.0 psi, 11.7-11.8 A/F Ratio

Seems like the charge motion deletes have been a problem with tweaking out tunes. I read about Fabers problem with the plates and his cams. Great to hear you got it fixed! Nice numbers!

I forgot my camera when I went to the dyno today. 
I'll be taking some vids of the car soon, though.
Well, I still have the plates... they were turned OFF in the tune and staying closed through the entire RPM range!
I've heard of problems, too, with the delete plates. Mostly with plugs fouling. Seems the plates help keep the air turbulent and therefore help keep the plugs clean.

Thanks! And at least SOMEBODY likes my avatar!!
Feels great! Even better after today's tweaking (and of course with the added 3psi of boost). It does come in nice and smooth and barely any boost is lost during shifting. The best thing is that the tune is still conservative and very safe.
I can drive it all day long as a N/A car, or step on it and GOOOO!

Needs to be more Astony
Awesome you got this resolved. Thanks for sending the pm update.
I knew it wasn't the WG.
This will teach a few people to double check things people forget about like the charge motion plates.

Awesome numbers Tom...that is one potent pony you have now.
I will go out on a limb here but after everything you have been thru it seems your problem really comes down to human error. Not sure what human deserves to have the finger pointed toward them but I am glad you finally got -r- fixed. And I also like your avatar!!

Congrats Tom - Sounds like you got it figured out. I'm still going back and forth - My tuner had the package I was going to buy in the shop the other day(customers car). Liked the packaging but the tune that came with it was junk....so it sounds like it could be the same issue.
It shouldn't be too long before I decide which way I'm going...best of luck...(and I dig the mouse!)

Awesome! Congrats on the HP and TQ numbers, I am very envious. And I'm still waiting for my ride.
Oh yeah, and the MM rat-atar has to go. What's next, big mouse ears on your beautiful white car?

I like the avatar Tom
And you like Mickey and they pay you so its all good.
Congrats as well on sorting out the turbo install. I knew you would get it all sorted out.
You are one of the few here at TMS that are incredibly gifted as a mechanic, problem solver and their attention to detail. I've always trusted your judgment and thought process, its very sound, and well grounded.
Good job, no send me the $20 for saying all that like you promised.......................Just kidding
