My car
87 iroc 3500 lbs with driver.list of Mods in sig and vb garage.Trans is acting UP.
25,00 miles on engine.10.5:1 cr,New ZZ4 revised casting heads,Lt4 production cam with 1.6 full r.r.,new gmpp block and internals,2500 stall,3.42 gears,shift kit and vette servo,hooker 2460 headers into custom dual 2.5 y into 3" i pipe,afpr,msd digi 6,flowmaster muffler.Basicly stock tpi.255/50/16 rear bfg g-force,Best timeslip I can find was an 8.8 1/8th which was before gear,stall,header swap.Most were around 9 seconds all on street tires.
I know the bmw is about 2 or 3 hundred pounds lighter and the trailblazer is much heavier.His g tech was giving him around 10 second 1/8ths in both vehicles.Ive driven the car and its a quick car but with a good launch I think I got him.Not sure about the truck,i need to resaerch it.
I may put him off til I get my intake finished porting and get my new injectors in.

Brian at tpi chips did my prom for me.I did some dattalogging and sent it back in a couple more times to get it dialed in a little better.The tpi is stock as of right now but not for long.Just need to finish up a little more porting a slap my new one on.
Sounds like you have a pretty good shot, however I have seen some of those new Trailblazers get down right nasty with almost nothing done to them. But if it's mostly stock I'd say you're still in good shape, IMO anyway.
