Hey all,
I recently had a cam/converter swap done on my 2013 Corvette A6, and I was a little surprised by my 1/4 mile times...cam is a Stage 3 by Bourque's Hot Rods: (23x/24x .62x/.61x 115), converter is a 2800 stall ProTorque single disc that I'm not locking at any point during the runs.
here's a vid:
Maybe my expectations were too high.
At the same track last year, mid summer (similar DA), I was running around 12.6xx, with 2.0 60'. Now, I'm running 11.99x with 1.89 60'. I kinda expected more of a gain here (there are guys on CorvetteForum running 10.9 passes with similar power/mods), so I'm thinking something may be off.
The two runs in the video were back to back, both 11.99x @ 119, preloading to ~1600 RPM then rolling into it - no spin at all that I could hear or see in my datalogs. I did one run just flashing the converter without preloading and it spun the tires all the way through 1st, so I'm thinking that may give me a stronger launch with DRs.
Here's datalogs of both runs, as well as my engine/trans tunes, pids, and dash pages: https://www.dropbox.com/sh/v7lq4nsht...sLD9WWYwa?dl=0
Is something off in my tune? I don't see anything that raises any alarms in the scans, but I'm fairly new to all this.
