Stephen, I no NOT think for a second think that you would release any kits with any known issues nor ill intentions. I've heard nothing but good things about your character and business relations.

However, there is definitely more than one case of the Stage IV-GT not performing as expected, hence that's why it required for you guys to fly out to Chicago, or make changes, etc. My coments elluded to the opinion that perhaps the kit was a little permature in its release, resulting in cases of the unexpected sub-optimized tuning states we've been seeing on this forum.

My post was more directly at offroadr35's complete and utter misinterpretation of my statements.

I agree. I had no problems with my black awd turbo with stage 4. Loved it. Wished at that time it had more power.


We have been relooking at the program. We have tested several changes from Kansas City and AZ and are looking into the Ryan's newly developed issue.

Ummm, this is not a new issue. This is what happened from day 1. It just seems worse. The "numbness" happens around 4800 to 5200 RPM somewhere. The car just stops pulling. I am not sure what you mean by differences between AZ and Kansas, but People with STage 4GT's in FL have the same issue. The ECU should adapt, and I doubt variances in Humidity would throw it off that much. I drove a Stage 4GT in FL, and it replicated my issue.

Finally do you really think that if there was any known issue we ever would have released a kit.

Of course not. I have been promoting your companies from day 1, and still feel comfortable moving forward with my Future Porsches with your companies (Imagine and EVO) - I am just a little concerned that this issue is lingering. Mr. Garrett - the programmer, needs to fix it A.S.A.P. before I go insane. There is no excuse for this program to STOP pulling at a given RPM Range.

We all were happy with the last trip to Chicago.

Really, what airline did you fly?

Well, Thanks StephenTi ..... so much for the sale of the Stage 4GT package. I guess I'm stuck with it now.

 

i did not even allude to your statement at all except to say that you cannot compare a 640-700hp program for use with new turbos to a 500hp piggyback chip. If you wish to argue that there is no difference in complexity and that there should be no difference in expected reliability of the two then you are an idiot. I, however, do not think you are an idiot and do not think you truly believe that. i suspect you misunderstood something that i said.

 

There are obvious differences between the two. It is merely my opinion that more R&D should have been done on the Stage IV GT before it was sold, that's all.

Shank: Sorry about the sale thing... my bad. You've got email...

 

that i agree with and is obviously the case. all i am saying is that when you start getting to these super high strung tuning packages, you're increasing the chances of problems like this exponentially. i am not at all surprised that the tuning is somewhat finicky. I do, however, have the utmost confidence in the GIAC dealers to get it perfected as quickly as possible.

I think we are saying the same things. Sorry about things getting off-topic Shank. you may want to just close this thread and start over.

-Steve

 

Heya Shank,

I know you've spent good money and I can udnerstand your frustrations etc... I do think you're doing the right thing, just give Garret/Stephen/Todd the chance to fix the issues. I bet it'll sort itself out

The GT2 is a different beast is all Kinda like my tip with Kevin's turbos is "different" too. I'm gonna wait it out

PS Do you any pix of those tech arts on your old turbo? I'm thinking of getting a set of wheels (2nd set)....

 

This will be my last post on this thread, as I agree, we've totally hijacked Shank's thread... sorry Shank.

At any rate, there's a big difference between experiencing problems due to pushing the limits vs. not doing thorough tuning prior to releasing, which is what I think is happening.

Todd/Stephen obviously have put out very reliable and powerful kits in the past, so I am not second-guessing their their skills nor intentions, but simply voicing my opinion that 4GT was prematurely released before all R&D was completed.

And, this very well could be because people are pushing them to release their products sooner than they are ready to due to their previous success. Again, I don't doubt their abilities, only that 4GT may not have been quite ready for release.

Peace,
Stephen

 

P.S. I sincerely hope that they get all the bugs worked out of the 4GT. The potential is there, just look at their own cars that they've been able to fine tune extensively. I don't doubt that I'll be going the big HP route in the future, and 4GT will be considered (assuming they'll even sell me a kit now, lol).

 

sorry shank I didn't mean to hijack it either.

 

Define "super high performance"

Let me first preface by saying that Stephen and Todd are good guys and would never have any ill intentions. Personally, I like them both very much. This critique is nothing personal, I'm just trying to share my insight so that they will have an impetus to make a major revision to their tuning programs, not just a software change with GIAC.

Problem with 4GT is that IMHO it's really not engineered properly and the turbos are not sized for the goals that they are trying to achieve. What it gives you is HP bragging rights, but as you can see from the results of the Shootout, HP and performance are two different things sometimes.

But, no one seems to want to listen, so oh well.

And Steve, just so you understand, you can't even begin to compare the Ruf Nardo to your Stage 4. Your car would get smoked, even though both are rated at 600hp. You get what you pay for, is the moral of the story.

 

I can't believe that a stage IV GT is as fast as an upsolute unless the Stage IV GT is not running correctly. A chipped k16 car should be nowhere near the stage IV GT, what is up with that?

Another thing, what are the issues with the Stage IV GT package? I thought there were many people on the board with this package and happy with it. From what I read here, it sounds like it's in beta.

 

Ever hear of a Mirage?

 

eet.

Ryan,

You need to look into the Nardo package. It is not really for the street. It is designed to be an autobahn bomber. That is to say top speed for long periods of time. Not really a great performer around town or our highways.

 

Hey guys, as much as I love to toast Garrett and EVO modified cars, I believe all of you off base regarding the 5000 to 5200 rpm range.

Every 996tt motor I have ever seen dyno'ed does this in this range too one extent or another. It is noticable. I'll give you a little hint. Why do you think we added nitrous and set it to start engauging at 4400 rpm's with full feed by 5000 rpm's? My personel observation is it has nothing to do with tuning and everything to do with the change over of the vario cam. Hell, KA still has a hick up in this range. The solution is to change gear ratios to stay in the sweep spot and and learn how to drive (shift) your car.

Hey Stephen and Todd, if I am wrong and you figure this one out differently, please let me know what you did.

 

Most of the dyno sheets I've seen of stage II (whether Upsolute or GIAC) looks similar to this... no holes. Perhaps the power dip is realized in higher hp stages? Not sure...
