MJC123,

Bingo! You have only to read Dave Colman's article (April Excellence) about my car to understand. Extra tenths become very, very costly. Most people would not appreciate it or simply are not interested due to the small gains versus the large costs.

 

Why buy a C4S when a WRX STI will wipe it out in virtually all performance comarisons?

Same type of question. Same type of answer.

 

Heheh I HATE those darn K24 hot sides Laggy effers! I wasn't sure what hot side's you were using on the blue car but it didn't seem to suffer from much lag... REZPEKT.

PS I went out yesterday and because I didn't do back to back runs and drive around the track between them, like a FOOL, I didn't get heat soak and trapped 127.8 yesterday at the drag strip... A lil' betta!!! Thanks for the REZPECT, I seriously don't know how to explain to people that it's much more than a matter of turning the boost up etc... And yes Garrett's boost maps ROCK. When you have a bunch of different mods all working together, you need to software that matches up nicely- it's just as important as bigger turbos etc... Can't have one without the other.

 

Why? Certainly you own a house worth at least half a million, yet I bet you have cheap 10 dollar Sears hoses and probably shovel your driveway with a 10 dollar shovel.

Paying more does not always equal more. What I see from the expensive “chip� camp is a purposeful attempt to differentiate themselves based on price alone, along with some vague explanations as to why their product “could be� better. In marketing terms, they are using exclusivity and snobbery to sell their product – and apparently it’s working quite well given the support those who buy their product are willing to give, with no real factual information to back up their opinions.

Is the GIAC system any better than the Upsolute approach? Who knows. Not you, nor me, nor anyone else here. For an otherwise stock 996TT, I would really doubt it.

The only reason I am personally considering PorschePhD’s approach is location – there are no upsolute folks near me and I don’t fancy the idea of taking out and then shipping my computer to someone I have never met.

Do I think 3500 is a bit out of line with regards to the changes they make? Yes, very.

 

I somewhat agree, although I'm sure there are at least a few here who have tried both products on the same car and can tell you that, based on THEIR experience and opinions, one product is better than the other. If 10 people all did the same thing and all came to the same conclusion, that might give the rest of us a pretty good idea if one product was "Better" than the other in terms of not only absolute power, but drivability, etc.

I do however agree 100% that $3500 for a chip is insane. There is no reason that anyone should charge this much for a chip, aside from the fact they know that 996 Turbo owners have money and can afford it. That is not "wrong" I just do not think it is a very ethical way of running a business. Basically gouging the customer just because you can. Of course in the end the customer does have choices, and if they choose the $3500 option over the $300-500 option than that is their choice, whether they made the choice knowingly or unknowingly.

 

Steve I believe that once you meet Stephen in person you will understand why so many of us insist upon going with him. His knowledge, skill and personal qualities are second to none and matched by his products. He backs his talk up...

PS Stephen time for a new sticker eh? 640t? Heh with 570rwhp time for a new one lol....

 

Hey guy's. There is and there isn't a secret here. The secret is no one is telling the numbers they are mapping. I really get a chuckle when everyone compares power and torque numbers. Like most people will say, "anyone can make power by raising the boost." The shootout made this real clear. Not so clear was how many can make power with let's say 1.2 bar? I know Protomotive did. Protomotive also mapped my first motor with 636 rwhp @ 1.2 bar. My guess is most of thse motors running high boost would not come close to 636 rwhp utilizing 1.2 bar.

Inquire as to what intake manifold pressure is being run along with the octane of the fuel being recommended. Armed with this information, you will be able to make a far better decision as to who has the superior product.

 

180$ boost controller

 

Soon2be993tt,

There is a little more involved than a boost controller to get to 1.4/1.5 bar. Besides the turbo's, waste gate springs and 1.3 bar throttle body shut down on the ECU.

"You retain full adaptive control and no check engine lights or temperamental MAF threshold issues. The system is a closed loop system which means the 02 run closed information the entire RPM range. This allows the adpativtive control to remain intact through the RPM and keeps safety measures in place without tripping codes. Hacking codes does not do this and locks maps and will compromise the overall goal of the 7.8 system."

Does this mean thet the Upsolute does not have full adaptive control and safety measures? Does it loose it's learning ability? Will the ECU respond to the knock sensor and make adjustments like the stock ECU with the Upsolute or GIAC?
My experience with tuning carbureted cars is that to improve driveability you richen the mixture. Does the improved driveability of chipped cars richen the part throttle mixture to the point that spark plug life is compromised?

 

I am not sure what Upsolute does, rather was speaking in general about programming in general and what we look at for our systems. GIAC remains as factory in regards to control and adaptive nature including the knock sensors. The 100 octane programs to alleviate the thresholds enough that 100 has to be run and nothing will adapt to say a 93 octane in the tank when set for 100.

No, if you look at what the factory runs AFRs you will understand why they went to a different plug to avoid fouling. The richer the system does not always dictate that drivability will be good. Often at idle and cruise you will find the AFR is rather lean, then on tip in will fatten up. There are about 7 different factors in the tip in and acceleration. The other factor is the whole thing is not always about AFRs, it is the rest of the data that goes with it. Knock activity, tempatures etc. You can have a good AFR and still detonate.
