Stock my car put down 224hp and 242tq. Tune only it did 261hp and 315tq. With the addition of a TRS intake tube, catch can, and down pipe the final numbers I got where 272hp and 317tq. I thought peak numbers would go up a bit but after driving it I can see where all the power went. There is almost 30hp and 30tq increase between 5k and redline. It's impressive! The car used to fall flat on its face after 5k or so but now it pulls just as hard all through out the power band, huge difference! A 6th gear punch now feels like what 5th gear did on the highway. Its a completely different car yet still pretty quiet until I get my foot in it. Very happy with my choices!:yup:

So how do you pass emissions? IE - O2 ready status.
There are two ways to handle issues like this.

First, keep in mind that ECMs are used in multiple cars, so the sensor inputs are designed to be flexible. If the ECM is used in a 4 cyl, only two O2 inputs are needed. If the ECM is used in a V6, it has to be able to handle four O2 inputs. So the ability to either turn off a sensor input all together, or have an error ignored is needed in the ECM. The default state of the ECM is to assume that everything is working fine. The ECM does not look for affirmative answers that everything is good; it looks for things not working correctly. When it runs a test and observes an error, or when a sensor value is outside a normal range, the ECM has 3 primary options: Report an error immediately (i.e. the SES lamp is turned on), keep track of the error and see if it goes away (known as a pending error); do not report the error. Telling the ECM not to report the error means no problem is shown. So if the error code for the post cat O2 sensor were set to report no error, when the car is scanned then no problems will be stored in ECM. The plug in emission testings looks for problems stored in the ECM. If the ECM says there are none, the car passes the test

Second, some tests can't be run until the car is warm or environmental factors (e.g., IAT > 0*f) are present. In that case, changing a criteria (e.g. run test when coolant is 160*) to a value that will not occur (e.g., coolant = 320*) prevents the test from being run and a negative result (i.e. error) is never generated.

Yes, at wot you can hear the turbo hiss a bit more. I think the intake and the dp work synergistically together opening up each side of the turbo. I had the intake on first before I put the dp and the tune back on. ( I turned the car back to stock to have the dealership check and make sure my car didn't have any piston issues) I could tell a small difference for sure and you can hear air moving through the intake at low rpm's......it sounds a little meaner now with all the parts on but its not a huge difference.

^^^^ You think that is bad... Price a set of high flow cats for a Hemi and figure cost per HP. Also you have to look at how many vendors are producing High Performance parts for the ATS 2.0T. It's supply and demand.

I added a set of SRT 8 shorty headers, a set of Magna Flow high flow cats and a Corsa cat back set of duals, all used and still had of over a grand in parts. Parts new would have run probably $2,500. I did my own install and saved probably $500 in labor. The result was 362 RWHP/387 FPT on a 6 speed stick. The stock rating is 370 hp at the crank.

Only 11hp from a DP and Intake?...... :helpless:
Thats only "Peak" horsepower..........your only at peak horsepower for a split second, horsepower under the curve is what was substantially increased, almost a 30hp and 30tq increase between 5000rpm and 6500 rpm, the car has WAY more top end compared to the tune only. The car is substantially faster, especially on the top end. Very happy and no reason to shake my head.

Hey, I was just wondering what this setup cost? I was looking online and saw the intake a catch can for $349. Is there a package for the downpipe and tune? Also, did you have a shop do the tune or was it a plug-in tune? And any issues with the car at all since installing the mods/tunes?

Thanks alot!
