Supercharged VQ37 goes BOOM!
Now, if you were to cam the engine, or changing to higher compression, its a different story. At the end of the day, its just a VQ with more air going into it.
Tuning is tuning. Changing parts doesn't make it "easier" or "harder" to tune. All you're doing is changing how much is flowing into and out of the engine. They're parameters, just like fuel and timing.

All that's done is an alteration to the mass of air entering the engine, which is the same as the GTM kit.
Both of them use larger injectors.
Conceptually and mathematically, they are identical. Just the execution is different. In both cases, ALL aspects of the engine are identical mass the volume of air which is entering due to the nature of the respective blowers, and the injectors used.
Saying that the Stillen kit is harder to tune than the GTM kit, is like saying a setup with GT30s is harder to tune than a setup with GT28s.
The car doesn't care how the air is getting into the engine. Just how much is going in, what temperature it is, and how much fuel is available to combust with the air.
How is it more difficult to tune?

Have you noticed they relocated the dual Maf sensors.
All they do is read a voltage, which is translated into a value. Location doesn't matter, as long as the reading is accurate.
Don't they read the air intake temp also and adjust air fuel accordingly. So what if the air is actually hotter than what the Maf's are reading

I am stock and have neither. My only mod is a radar detector.
I am just curious. I just fail to see how any one kit is more reliable than any other. The only way you can talk about reliablity of a kit is reliability of the actual parts themselves, not blowing a motor. The only possible way to blow the motor is a faulty tune, which someone could do with any kit.
If a part broke and fell in the motor I would agree. But you cant blame the inability of someone to properly tune a car reliabily on the kit. That is just like saying the kit is unreliable because it wasnt installed correctly.

Ok seriously guys, why are you all bashing the points Weiboy is trying to make. I'm sure non of you have the experiences that he has had. In fact, I'm sure he is the only one who have had both kits on his car, and according to him, the GTM kit does the job much better. This is a source that i can rely on, user end feed back tell problems that just can't be explained on paper.
Altho, in my opinion, this might have been caused by the stillen kit itself, I don't think it's because of he added a header which caused the engine to blow up.

MAFs read air mass, so temperature is not a factor in the accuracy of the reading. Temperature doesn't affect the mass of air, but it does affect volume and/or density. (this is a really watered down explanation)
the kit does have some quality in it. Some parts are pretty well made but I would still won't recommend another member to buy it. I'll upload some pic's later on tonight and let you see.
Thanks, I think they're just trying to make a point saying it's all in the tunes. What I'm trying to say is how can you tune something that have flaws in it LOL

Stillen's kit uses an UpRev canned tune with their "turn-key" kit. UpRev uses the MAF sensors to actually tune the car, just like a factory tune. Think about it, we buy these cars worldwide; different elevation, different gas, different variances.
When you're tuning the vehicle, the MAF sensor is compensating the air, so if you say at full throttle I want to keep it around 11.5 - 11.6, then the MAF will compensate the air/fuel to see as close to those measurements as possible. Why do you think when you go with GTM's turbo turn-key kit, you don't need a custom tune sent to you if you decide to add test pipes, a 3" exhaust or anything else (thanks to the blow-through style MAF setup)? A lot of it has to do with Timing too. If you don't have an aggressive timing, you can get away with extra mods without needing a new tune.
What I think the issues is... the pull-through MAF system. You're not getting an accurate measurement of the air that's reaching the engine because it's being changed when it blows through the charger.
I've done a lot of research on this and there are a couple members I'd like to personally thank that have given me great insight on their review of this kit.
I could be wrong though :stirthepot:
