Holy crap zzp pcm tune
thats a good deal, I didnt know you guys were willing to adjust tunes. When I hear canned tunes, I think they are "as is" but this is good to know in the future.
I got a "canned" zzp pcm tune last week on my stock 09 cobalt ss/tc lnf and holy ****, it's like night and day now. Before I was only boosting to 18psi max and now I'm hitting 25+psi and can do a burnout in 2nd and 3rd gear. I didn't think the tune would be that aggressive. I'm literally bone stock besides a drop in k&n filter. I guess these LNFs can make some freaking power. My next purchase is gonna be projector headlights with halos.
And I am certain the tires are crappy. I think he mentioned the car only has 6k miles. Meaning hes on the stock junk tires.
I have their canned tune and I'll spin 2nd after 4K and then 3rd just grabs all day. 1st gear is still useless and you have to really pedal it, even with reduced boost. I have new DZ101s at 29psi upfront.
Yeah I can't get traction from the start at all if I'm racing somebody, I'll spin a little in 2nd then 3rd just goes and goes. I think these cars just suck from the starting line, at least mine does lol

Intercooler/charge pipes are not needed for stock turbo. Only time is upgrade is IF your stocker breaks or if you go bigger turbo. Some people cry you need them for reliability but its rare to bust the stock charge piping and the stock IC is overkill for this car, unless you smash it on something then might aswell go after market since price will be similar to stocker.
Add more boost to brittle plastic = Pop. I see stock piping pop all the time at anything near 24psi.
Plus what KMO said. Flow is much better and I assume temps will be much better on a new intercooler. Worth the money to upgrade.
This doesn't seem right. I don't know exactly how these sensors work as far as voltage range, but fundamentally the MAP sensor outputs a voltage for a corresponding pressure input. I'd think that if you have the same pressure input the voltage output would be different for the two sensors. Meaning the tune would need to know which sensors are giving it info. It may be low enough of a delta that it's not very noticeable, and if the PCM thinks there's more air than actual you're just going to run rich or have more trim. Again, I'm not experienced so I could be wrong.

Off-topic: Did you change your name?
Do they have the option of stock sensors vs 3bar? As long as it's specified then i'm not sure why there'd be any issues.
NEVERMIND, i just read the post above. The question made it seem like he was asking/suggesting running the same tune with either sensor.
