Custom Tuning Results/Writeup!!
I apologize if half of what I am writing does not make sense, as I just got home and it is after 2:30am and I have been up since 8am.
Today I got my time with a Cobalt SS/SC 2.0L and it was fun. We picked up great power, and kept stock drivability and reliability. The issues of hanging rpm's at idle, part throttle are due to the ETC and HP Tuners does not have these functions yet so they will not be able to be fixed at this time.
The vehicle I worked on was a BONE STOCK 2.0L Cobalt SS/SC. The only modification was NGK V-Power Plugs 1 Step Colder with a gap of .035.
Alll comparison dyno runs were made with equal cool downs and multiple pulls to ensure accuracy. The numbers do seem high for the modifications and even the stock numbers but remember gains are gains the final number just may be a bit high.
This tune was done on 94 Octane. With our custom tune the vehicled ran a lot colder, with ECT temperatires dropping to a consistant 150-170 whereas stock is up and around the 240 range. IAT2's were about 15* colder than stock. With the injen cold air kit, IAT2 was about 4-5* colder than with the stock air box and yes, we were able to get proper readings for IAT 1. The car feels totally different from start to finish. I will have the customer post his thoughts and reactions in this thread or another
We will be offering these tunes, as a direct flash with no dyno time for $275.00 + tax's. Custom tuning fee's are $550. We will not be sending these files anywhere outside of the shop and all tunes are locked which means no one else can suck them out or reflash the pcm, including the dealer. If any fixes from GM come out, we will be able to update you. We apologize if this causes any trouble but we have put to much time into our tuning process for these vehicles to simply allow anyone access to see how we control everything
Below you will see how important it is to get a tune in stock trim and even after putting on a cold air kit.
This first graph shows the power gain over the LATEST GM Stock Flash with all fixes:
Below shows the difference between stock air fuel compared to our air fuel. This was measured BEFORE the cat using an AFM-1000 Air Fuel Meter calibrated before the dyno session:
Next we added the Injen Cold Air. As expected, the air fuel leaned out because of the larger diameter mass air housing. More tuning had to be done to get compartive numbers. Below is a comparison between our custom tune air fuel ratio and what happens when simply adding a cold air
After custom tuning, we ended up with a clean air fuel of 11.8-12.0 as we have with the stock air box.
Below are power gains of the tuned .vs. intake with tune:
Finally, the complete package. Injen CAI, Steeda.ca 94 Octane Custom Dyno Tune
Attached are some random photo's of the process. Any questions, please feel free to ask

Not only is the power huge gains, driving the car is way better. It runs way cooler and smoother. We will be doing ALL GM vehicles but one step at a time

Nothing really changed in 07, so as long as your VIN is in the database this tune applies to you.

We are offering our tunes for $250 which is extremely affordable and takes away all the headaches of having to tune your own vehicle.

If you want, bring the car by and I can compare the stock tunes/ They may have changed some things, but the motor, blower, etc is still the same

I am at the shop Mon-Sat.
For a good, safe reliable tune distance is nothing. We get customers from Calgary, Halifax, New York, New Jersey, Detroit.
There is a lot more to tuning than what you see from air fuel and power. Let me know how I can help

oh and I know how much more there is than just AFR and power.... I have many many many hours into my car on tuning alone.... sucker runs bad-ass and I drive it to work in manhattan everyday... so driveability was a big issue with me.,... but all is good... I just need to smooth out my afr...

great numbers....but kinda hard to believe since intense, zzp, etc. have been working with our cars for a while now and haven't seen anything like this. Do you mind posting the log files from HP Scanner?
Intense Stage1 only make 235HP and you made 244HP, hmmm?
