2 more cobalts get trifecta tuned!
I tuned a 2 door and a 4 door last Friday. Both are In a 22 psi tune and both love it. Both cars are at 0 degree of knock. The built in LCD gauge that you guys have (Which is bad ass) is pegged at 320 hp. Before tune it hovered at 260. I have a 23.5 tune for both, but they seem to be loving it right now. Hopefully they will chime in.

The RPD seems to be no longer accurate after tuning. It was showing me making like 310 hp and tq. Not quite pegging it out, but I dynod in the area of 330whp 360+wtq

I have the GMS1, and my RPD pegs me at almost 300, and my dyno numbers are in my sig. But I have since gotten the Hahn Mod Pipe with an E-Cutout on there. So the numbers in my sig don't reflect that. So I should be about 300 to the wheels...

Man I've had the money for a Trifecta tune just sitting there for a few months and I am very heavily leaning towards a mild Trifecta tune but there is a little nagging voice in my head saying GMS1 = Warranty

Won't the ECU learn it down though as GMS1 supposedly dones't get rid of learn down?

Same numbers from your old 22psi tune to the new 24psi tune? Did you dyno YOUR car yet or still claiming what Blueberry got? (which he admitted wasn't actually your exact tune like you claimed)

After running faster then you with less parts and less boost and never coming close to that whp, Im very interested in finally seeing this dyno graph.
Edit: And yes, Im still hung up on numbers Term LOL! If it was 5-10 whp, NO issue at all. We're talking 30-40whp difference here tho.

GM stage one changes the tables that determine the desired boost. It raises the desired boost and airload levels so in a sense it still has a target boost and airload level (What everyone calls the "Learn Down") but it is set higher than the factory tune. The GM stage tune is still very conservative when it comes to the desired airloads, max airload torque settings, and timing so it is a mild tune.
