Trailblazer SS Tuning
Dan, I'm not saying you did any thing funny or intentional to start with low baseline #s. So far in this thread, we have 2 real world tuned TBSSs, one did 331/347 (tuned by LS1speed) and yours did 336/352. Those are pretty close. But because of a vendor on another forum promising 40 hp gains with their mail order tune, I've been asked by 2 different TBSS owners if I could get them a 40 HP gain with a tune like that one vendor is promising. One was the owner of the TBSS in the graph I posted. Do you think that vehicle could gain 40 HP with a tune? That would put it in the 365 HP range. I don't think so. Could it reach the 331/347 ~ 336/355 range? Probably so. That's the only point I was trying to make here. Unfortunately some people will only concentrate on the # gained figure they read rather than the final #s.

So I will let you guys know the results

So these run 13.9s with that stock RWHP then gain 30-40 on just a tune? Wow can't wait to see someone tear into one with mods. Can you say family haul'n lightning killer? How much ET do you think is lost in an AWD model?
Wow. Too bad I dumped all this dough into the Z. I could of had a 12 Sec daily driver that can tow a boat. Oh well. imagine what it would do with a KB or Whipple. 11 sec, boat towing DD.

My quest is how well will it do with a smaller stall or even a stockish' stall.... will need to up on the power but she should definitely run real sweet with a h/c.
Now imagine a blowen 382/370, 9.0:1 CR with a turbo/Kenne Bell on top.
I would like the kenne bell for the TBSS.... that would be a great DD and like you said, tow a nice size boat!! Let see that silly Jeep SRT-8 tow a boat, the most it would do before ruining the trans would be a cart full of groceries!!

mine (2WD) dyno'd at 326/330+ after my Wester's Garage Flash tune (15 pulls & 4 different tunes) we got 352/370 on different runs (3 in a row) truck made from 347-352+/ 363-370+ my graphs are hard to read, but I willtry to post them again ( cant get the dam "bitmap" image right)
also my truck ran 13.5's all day long in 40* weather and good air, best of 13.49 @102+ (highest MPH was 102.5) with a 2.02 60' bone stock..
in the heat, before the dyno session I had a tune in there with only 10/10 HP/TQ gains over stock (proven on the dyno) in 75* weather & bad air (DA was 2200') and went 13.52 @102.54 with a 2.05 60..in some good air and weather, it should be in the 13.3's maybe better, nothing more than a tune..(factory replacement K&N was in there since new)

Dan I am not doubting your information at all. If it helps any that is my dyno chart that 2XLS1 is posting. If you look at the run number you can see it is run #6. That is the 6th and final pull that was made. All pulls were made back to back. The first run the SS downshifted so the numbers were off on that pass. It actually made more hp on the last run than the second run. Runs 3-5 were made trying different things with the air intake. So I guess mine more power hot. I have yet to see a stock 2WD dyno less than 320. I don't know that I have seen any with muffler only dyno though.
2XLS1 I am waiting with money in hand for my extra 40hp from my tune.

Crash02, show me the money...
Bottom line....... TBSS gains a lot of power from a tune.
My brother gained about 30 rwhp from a Predator tune on his.
But, when vendors start promising 40 hp + for everyone.......... They're feeding you the same crap thate EVERYONE trying to sell you something is feeding you.
TYPICAL gains and AVERTISED gains are tell two very different stories.
Take the best #'s you've seen, then multiply by 50% to get a realistic idea.
If every ls1 car started with 325rwhp stock, and lid gave you 10hp, cold air 15hp, catback 15hp, headers 40hp, tune 20hp, intake 20hp, MAF 15hp, ported throttlebody 10hp, pullies 5hp.......
That's 475 rwhp with just bolt ons!!!! (560hp at the crank!)
Get the idea?

Check out www.trailblazerss.com. There is actually one running low 12's and there is also one running 11's. These things cut awsome 60' times with a tune, converter, CAI, and a nitrous kit. Like 1.5's and 1.6's. Thats one fast SUVette

I mean don't take this the wrong way but, sometimes I wonder why we go on the message boards at all, it seems like if you tell the truth people don't believe you. Would it of been better if I went on here and completly lied and said it only had a 10 horse gain? It didn't, it gained what we said it did, bottom line. Anyone is welcome to come here and watch this truck on the dyno.
It leaves me kind of puzzled, what should I do next time we some gains that are not the norm?

People just love drama on tech... 
I am gonna side with Dan on this. I just had my TBSS dynoed today on a dynojet and it only baselined at 287hp and 299 tq. 3 pulls all within .5 hp.
GM apparently left alot on the table with these. a good tune could be getting close or at 40hp gain setting it at the 330/340 mark.
