Thanks Scott. You input is always appreciated. Maybe with the added power you would benefit from some more rear spring?

Don't know. I've used rears as stiff as 650 lbs without the GMS1. I'll probably try other combos in the future because I wasn't overwhelmed by the last setup. Some of this depends on whether or not an added rear sway is of value. I've had a hardcore bar on order since last December and I'm still waiting on delivery from OTTP.

So, based on what's going on in SCCA circles, it seems like others are asking the same questions and I think getting the same answers.

Final quick note: I loosened the LCA bolts on the right side (it was pushed back a little) and pushed the LCA back forward. I think this solves my caster issues.

good to hear you didn't have any permanent damage.

So, glad winter is over and racing season has begun!!!!

I hope they are listening to this stuff somewhere. I keep hearing these stories, Now I'm very hesitant to order from them. Gonna go full stiff on the rear shocks and see if I can go with out a rear bar upgrade until this issue seems to get worked out.

maybe the discussion shouldnt be is the gms1 a mod, when people can order it with the car new from factory and installed before it ever leaves dealer lot, since it is a build option would it than be considered stock!? its from GM not an outside source, and its listed as just an option on the 2010's and available for all 08 and 09's.....

I believe it will make a difference, because if i remember right the redline is increased from 6300~ to 7000~(correct me if i'm wrong please).

I know for the courses that i will be competing on that this will allow me to shift less. which i believe will impact my driving.

Last year i found i had to shift to third then have to shift back to second not long later, so im thinking this will make a difference.

Just my Two cents

Actually 6350 to 6500. Not that much. It went up to 7000 on the LSJ Stage I (I had one of them).

I race in the STX class and I have the GSM1.

tommyk 08-21-2011 10:03 PM

Not not try and beat this into the ground, but is there an official place where it says this can or can not be used in STX? As it seems, there is not. Does anyone know where to get an official answer of yes or no on GSM1 in STX?

I guess this falls under modifying the boost controls, though.


my gms1 has hit up to 25 psi, ussually its around 20-22 it does what it has to , to hit 280 /320 just like the stock tune does what it has to , to hit 260/260

Yes. You can't raise boost in STX, period. Can't do it. Therefore, GMS1 is illegal in STX. Run in DSP.

Guys, I have been following this since it started. The only way to know is to call Doug Gill at SCCA and ask. Additionally you can have someone protest you at an event. However instead of filing the protest, talk to the head person, hopefully Doug Gill will be there if it is a national event. Tell him the issue and ask if it is allowed.

I was going to protest a fellow competitor years ago. I talked to the competitor before hand. I believed what they were doing was allowed but nobody had really said anything. So at the event I made it clear that I wanted to protest. Then the head person came up to me and said they checked and explained that within the rules my issue was allowed. So if I was to protest, it would not be upheld. Did I still want to protest?

I had my answer and did not have to actuall protest anybody. The issue then was similar to ours now.

Traction control is what was then SM2. It is done by altering fuel and ignition and both are free in our class. My thinking if this issue was pushed if the Stage one kit is allowed or not, I think it would be as long as it can be shown that only fuel, and ignition are the only things altered and both are free in SP class. I have found no writting that states the kit manually or by computer changes the boost level. It only changes the fuel, ignition.

Just my 02. I also know that if your race quite abit, most of the top guys in each class know who each other is. If you are doing something and is clearly wrong, it should not be done. However if it is a grey area, none of the top guys will protest because they know you won because of your ability not because of fuel and ignition.

Just putting in my take.

If you want more power just run E85 with the stock boost. I allready checked with SCCA and its legal for all classes.

Been planning that myself. Hoping my tuning skills are up to this next year ;) My STX tune is so much more responsive than my high boost tune anyway.
