Calibration and Config files will not open directly from the site, they must be downloaded to your computer in order to open. I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

09 CTS-V not holding in 2nd

Still trying to read up on everything posted here. Great site!!! I was guided here by some fellow CTS-V forum members.

I had what I considered stage 2 mods. About 590rwhp. Had the car tuned. Ran very good.
I then had my blwr fully ported and some other supported mods(bigger hx and ice cool box-to help IAT2 temps)

From what I have been reading with my lastest mods and no retune(due to maf) could be a result in my issue.

first I notice when cold in D goign into 2nd gear it will flare up and then engage. Maybe happens 2 times when cold. This is very light throttle.

My biggest concern . I went to the track wed and 2nd gear was terrible. It would try to engage but seems to fall out then back in and then out. Once in 3rd all seemed ok.....even into 4th.

I am going to post my current tune and 2 logs from racing. one I had to let off due to some tire spin the other I held to the floor and you can see 2nd was not pretty.
I download the engine config and tranny config.

Should I load/copy over the 2010 ctsv file tranny stuff or???

Thanks
Dennis
