So I am currently trying to find out a little information for classing reasons.

I currently run in DSS (Canadian). I have an allowable 6 points. my current set up is:

Pedders Springs: 3 Points
Rear Sway Bar: 1 Point


So I run the Superchips tune off the track and flash back to stock for autox. I recently competed in DSP with the tune, and I love running with the tune (Almost had an FTD with it tuned). It is the perfect amount of power. I want to know if the superchips tune works the same way as the GMS1. There has been many discussions on how it does not alter the boost directly. I will be dealing with the same issue if I want to run the tune.

8.8.2. Alternate ECUs /chips may be used on normally aspirated vehicles. Alternate
ECUs/chips may be used on forced induction vehicles only if the ECU/chip does not
DIRECTLY alter boost settings. Turbocharger boost settings may not be
specifically altered.

My plan is if it does not alter the boost directly I will run the following set-up to see how it works:

Pedders Springs: 3 Points
Tune: 4 Points
Fire Extinguisher: -1 Point

Not sure how the car will react without the rear sway bar but I am interested in the different set up.

So, does the superchips tune directly alter boost settings? What are others set-ups in DSS?

 

Yes..

Superchips Programmer new boost level - just about 20-21 psi

Thanks for the reply ronn.

Just because the boost is raised with the tune doesn't mean the tune directly alters the boost though. GMS1 does not alter thr boost directly but you still see higher numbers. So I am hoping superchips is the same

 

Wow..if you can get away with it, that's..great. Higher boost is higher boost....doesn't matter how you *got there*. I'm pretty sure most clubs have you take a hit on elevated boost and that's only fair.

 

Sorry I think your logic is a bit flawed there. Most (if not all) tunes directly affect boost settings. Stock is 12-15 psi and no matter how hard you try to argue semantics, Superchips, Trifecta, etc all raise boost to 20-30 psi. This DIRECTLY affects boost settings and if you talk with an official, they will tell you the same thing. If you however find a way to have boost hit earlier and give you maximum power with the same pressure at lower RPMs, then you would be fine.

 

I think he's thinks *MECHANICAL* alterations (like shims in waste gate...blocking boost lines like *pill mod*) are what they are looking at. I'm with you..boost is boost no matter how you alter it.

 

We had this discussion a while back. The argument is that with any LNF tune you don't DIRECTLY alter boost. You change the desired airload.

8.8.2. Alternate ECUs /chips may be used on normally aspirated vehicles. Alternate
ECUs/chips may be used on forced induction vehicles only if the ECU/chip does not
DIRECTLY alter boost settings. Turbocharger boost settings may not be
specifically altered.

It's a stretch but not any further than people running R-comps as "street tires". I decided not to run a tune for STX. I would kinda feel like I was cheating and around here we never see third gear so I don't really think it would help much.

 

Thank you jboogie, this is exactly what I am trying to get at. I understand that yes it results in higher boost settings, but it is indirectly altering them. So I am wondering if superchips acheives higher boost levels the same as GMS1.

There is the link to the GMS1 discussion for those who aren't quite grasping what I am talking about.

 

It's damn close. You saw 20-21..that's a big increase over stock. That's what I run on my HPT tune and it's more HP (about 20 more) than GM1.
I still say if BOOST is increased it doesn't matter! You should take a hit. If you can get away with it..fine...but you're at an unfair advantage over stock boost cars.

 

An unfair advantage? not at all, everyone has the same amount of prep points its all about how you use them. You can supercharge or turbo your car if you want to use your prep points on that. A stock SS is capable of acheiving higher boost in the stock configuration.
