That's what I'm talking about! "Aftermarket Prep" :tup:

I believe the Shelby 500 also has beefed half-shafts on the rear-end.

I do believe they will do the right thing as well. They have pretty solid customer service. :tup:

And a very long history!

Anyway, I do remember Kyle saying way back when that 8psi would be the max amount of boost on this engine for reliability as a daily driver. Not like this engine is known for running cool, either!

This kit was tuned for a system WITHOUT hfc. Since your car HAS hfc, it doesn't surprise me you may be having problems. Did you not research the kit prior to purchasing your hfc?

Tom,
Go back a few pages and look at my torque curve. It looks like yours, except mine trails off slowly where yours take a big dip at 7,000 rpm. That may be that it's too lean up there and it's pulling timing because of the CARB tune? Mine has headers, cats, exhaust, but tuned for that setup. Everything on the dyno curve is really similar to yours except from 7,000 to 7,500. That is the best part of the power band with the FI vq37. I am happy with what it's doing there. It's the 2,500-5,000 part that is really falling short of thier press release, but that part of the powerband gets used a lot.
Kyle emailed me and wants my car back. He says, "I have some really good news for you. Our engineers worked feverishly last week and into the weekend to develop a new tune that we are confident you will be happy with. This new tune has significantly increased the bottom end and mid-range performance. Also, we have refined the tip-in and part throttle performance and drivability."

In regards to those saying this is a Stillen vs. GTM argument, it's really not. This is the Stillen thread. It's about what the Stillen kit is doing and how it's coming along. I post here with my results and my criticisms to inform people, to get educated ideas from the many smart people out there reading this thread to get some new changes moving and to keep everyone updated. As I said previously, the tune for the header/hfc/CBE combo needs some fine tuning. In the end, I think the Stillen setup will be great, even if I am frustrated with the way it works right now.

It still has that sick centrifugal whine, makes 500 hp and hits the traction control doing a 4th to 3rd downshift at 70 mph with 305 width bridgestone RE11's. That's not bad. But I want perfection!

great response Phim!

Quick review of Stillens new tune:
I just flashed a new tune Stillen sent me yesterday. It does have more low end power and much smoother in between shifts, no more of that jerk. Took it to the freeway and the tip in throttle response is very good. Picks up speed much quicker and doesn't have that slight bog no more. All I need to test is WOT.

Yaaaaaaaa good news!!! Go Stillen go Stillen lol

Yes i would love to see things ironed out here! Good job stillen.. Your kit is still under consideration.. Numbers plz!

thats good to hear

Good to hear guys :driving::tup:

Isn't Stillen going to have a warranty once Carb legal?

Yeah, if you have it installed by one of their certified installers I think you can purchase a warranty with the kit.

I have the Stillen SC installed and the new tune but I just got the new pully in the mail a couple of days ago. How hard is it to install the new pully. Do I need to take it to a shop or can I do it at home. Is there a boost gauge that will fit into the factory pods in the middle of the dash. I dont really need a clock there but a boost gauge would look nice.

^ from what i hear that stocker can be a pita to remove. Few people have had problems. If your mechanically inclined with the proper tools then go for it.

Im really jonesing for more power... i was ready to buy my rims and coils but they may have to wait. Lets get some numbers up with new pulley and tune.

so who pays for the labor of changing to thenew pully which Im sure will cost a bit. It seems after you pay for the install and then they replace something they should pay for the install.

Pulley change shouldn't take more then 20 minutes. If you just spend $1k to have a SC installed I would hope they would do a simple pulley change for no additional charge.

:iagree:

but if you are not at their shop any more then you have to find a local one and pay them then you should get reimbursed by Stillen.

We alloted for $100 to cover the pulley swap.. paid to the customer..

cool, good to hear, good customer service. :tup:

Josh,
I know being one of the first to buy a SC for a new car is never a good idea because there are always bugs to work out. I am glad that you are still working hard at Stillen to make small changes to optimize performance and stand behind your product. I have yet to drive the car but I will give an update in 2 weeks when I get home.
Thanks:tup:

It drives nice, you will have fun with it when you get back. :happydance:

Off topic, but that Avatar pic is Fing awsome, please tell me that is you in the pic so I can add rep because i love cherry kool aid.
Frank

No thats not me, I cant get that big or I would have to sell my car and get lipo suction.

Back on topic! I finally got a chance to wot my car this morning. Got up to 7k rpm with 7.8 psi of boost. That is very good compared to the previous tune where I only got 7.2 psi @ 7200 rpm. My boost starts building at lower rpms now. You guys will be very happy with this tune.

Around what rpm does it start to kick in now? So when cruising around and you step on it and go WOT how does it react? And with just normal driving is there more power there than before adding the kit? I guess what Im asking is, is there more power there at all times than there was before the kit?

Boost starts building up about 3k rpm. When I'm just cruising I don't even need to wot and the mph gets to 90mph fast without even knowing. The reaction is fairly quick and smooth you'll be surprised at how much faster it is compared to stock.

There is quite a bit of noticeable extra power compared to stock when just driving normally. Not a whole lot but good enough where you'll feel it. Just wait till the boost kicks in lol. That's when you'll hear the blower come alive! Hope this helps!:driving:

Cool thats what I wanted to hear, I want the WOT power but I also want it have more "just cruising" power than stock too. Thanks.

I know everyone likes pictures so here are a few my wife took for me. [ATTACH]Attachment 15052[/ATTACH]

Looking to do another build, Lou?

Hunter's Tuner kit arrived late this afternoon, and we will get started first thing tomorrow. Build thread to come :tup:

Whoop Whoop!!!!

When is Stillen going to comment on this. I know josh said a detailed write up was coming. I am glade they got it figured out though and stood by there customers. Also I think that it is wonderful they comped in 100 dollors to cover the chage to install the new pully.

+1 for stillen just curious as to what Josh and kyle have to say to what caused the problem
Frank

Josh or Kyle. How much is the tuner kit version going for?

I think they are probably enroute to Zcon.

Hey josh you havnt contacted my shop with a new tune yet. Do u guys have a tune figured out for me yet?

email him. His forum name is his email address

Oh boy......
