Ok. So I have not been on this forum in along time. But I have the GMST1 tune with all HAHN bolt-ons. 11-13-2010 I had my car on the dyno which was a dynojet. I had 91 oct pump gas and put down 303whp with 321 torque. I have been to the track and my best time in the 1/4 on street tires was 13.79 @ 105 mph. Honestly I am happy with my car the way it is for now and I'm still under warranty. I have never had any issues with CEL's either.

I have gms1 and full bolt ons I dyno at 272hp and 300lbs of torque, dyno was putting out low numbers all day but my best 1/4 was 13.4 at 107 mph with a mid- high 60 foot so either my dyno spit out low power #s or possible driver mod ... I'm also on stock tires with 17k miles so idk...
Oh yeah its a blast. Cant wait for my warranty to expire so I can run meth and a real tune to see what power numbers I can get on stock turbo.

When I was catless with GMS1, there is no doubt in my mind is added great HP, cel.. but didnt bother me.
With DP, could spin my tires anytime, low tank of gas or full, passenger or not, hot or cold.
Now completely stock, once in a blue moon I get wheel spin in 2nd - but still can smell my tires.. meaning they are on the absolute limit of traction and juuuussst catching.
So yeah, 10hp/10tq? probably.. just enough to spin in 2nd on command.
Trapped 108MPH @ 14.00 summer 2011 GMS1 + DP thats with a disgusting 2.7/8 ish 60ft
This winter im getting HAHN charge piping and intake (for the sweet turbo sounds, not for HP lol)
Im wishing overall it does at the least make the turbo spool ever so slightly faster like the catless DP did.

all i have is exhaust and a K&N SRI and turbo spool seems to be instant and fast. i have the upper charge pipe and a MPX intercooler,but am waiting until next spring to install them. does the charge pipe make the turbo spool much faster??

A few people say they do, but it's likely in their heads.

Muffler + 2 cats VS no cats and no muffler, positive there was faster spool, not enough that it would matter. Just like at extremely low RPMs the boost was a lttle more responsiive and fast - at high rpm extactly the same ... so the idea it helps to me wouldn't be used in any performance related scenario in the first place .. if that makes sense.

i dyno'd 268whp with just GMS1 and no boltons.. buddy of mine with intake/dp/exhaust/GMS1 dyno'd 271whp on the same dyno so it only made a marginal difference.
spool time maybe varies a little.

yea,i know GMS1 with bolt ons dont do much. only reason i picked up mod's was because my buddy was parting his TC out and i couldnt pass up the price lol
i was looking to get tuned and all that jazz but idk,i dont race much track or street and i am happy with GMS1.
i wish i would have dynoed bone stock with just GMS1 and then put all my crap on and then re dynoed
