Mild Mod 1/4 Mile Estimates

Have a big heavy 2007 Hemi 1500 4X4 QC. I ran it last year bone stock except a K&N drop-in filter and ran a series of 16.3's and one 16.2.

I'm heading out to the track on Sunday to try to win the Trophy class and I'm wondering what people think it might run... I've added the following mods:

- Magnaflow 12649 3" Muffler with front resonator removed
- NGK 5306 Plugs (not a mod - just thought I'd mention it)
- SC Flashpaq - will be running Perf 91 Tune

Any guesses on 1/4 ET and MPH?

Also any suggestions on setting up the Flashpaq? I've made no changes other than the Perf 91 Quick Tune... I don't have advanced trans management but any changes to rev limiter? Should I raise it? I won't be able to make any changes while I'm at the track because I only get 2 qualifying passes before eliminations begin.

What do you mean when you say " ... front resonator removed?"

You mean the catalytic convertor?

Nope not the cat... I'm not sure if it's a Canadian thing but on my 2007 after the Y Pipe there is some pipe then a resonator then a pipe then the muffler then the tail pipe with the resonator that's part of the tail pipe.

When I did the muffler I removed the front most resonator (just after the y pipe).

yup, it's a resonator (mds trucks have them)... my guess is mid 15's :)
