Vortech canned tune

[falconma]

Hey fellas, how extreme have you been able to go with your engine/exhaust setups while still using the vortech canned tune? I'm asking because I already have a catback and would really like to add some LT headers and H/F cats to my zoomers while still keeping the canned tune. What about porting the intake manifold?

I've known several people that have headers and Hi-flo cats and cat-bac with there Vortec with no problems..there are several people on here with it, they will chime in shortly!!

Hmmm.... I didnt want to go with the Vortech tune because of the fact that I had headers and hi-flows. I might try it out just for the heck of it and see how it feels compared to what Im running now.

ANYTHING in front of high flow cats.....i would modify the tune......anything that has to do with flow.....

Ok, so lets say I throw on the LT headers w/the vortech canned tune. Will it be safe for me to do some WOT runs and catch the datalogging data necessary to get a good email tune from a vendor like RDP or interia? Or will it not even be worth getting the full vortech kit w/tune if I will be just changing it out anyway?

Honestly, I think you're safest if you do these things:

1. Choose a tuner with experience with FI on the 6.1 AND other platforms
2. Install a wideband in the car, and monitor boost to confirm it's 5 - 6 psi
3. Have him tune on the dyno with accurate AFR measurement from both his tailpipe sensor and your in-car wideband
4. Log AFRs on the street to ensure they're still where you expect them to be.

Agreed. That would be the most preferred route for sure. However, I'm looking for a solution that allows me to install everything myself (with a little help) and not have to get a CMR tune. This is why I am heavily favoring the Vortech because I have not heard of any negative experiences with the canned tune.

I don't forsee any issues with Longtubes...if you did heads/cam etc then you would definitely need a custom cam. The L/T's may lean it out a tad but the tune is so rich to start with it isnt anything to be concerned about. As always I would still get it on a dyno to check it out and a wideband is always good to have when running boost.

Thats exactly what I needed to hear. Thanks SRT8U!
