Default Tune Question??

Totally new to this EFI stuff. I have a question that I searched for and cannot find an answer. I had the stealer put on my stage 1, SERT, S/E A/C, and SE slip ons. They did the dyno thing and all is fine.

Well I just cannot leave well enough alone and ordered a set of Vance and Hines dresser duals.

My question is will I need to have my bike re-dynoed after I install the true duals or should it be ok?


Thanks
Chris

Well need... you certainly will do no damage. Will it operates at peak performance, no you will need to re-tune, if that's what you meant by a dyno thing. Will it run good enough, probably but only you can be the judge of that.

Going from slip-ons to a tuned exhaust is usually a big change in VE for one cylinder or the other. I can't tell you if you will notice a change in throttle response. Its not going to hurt anything short term, but keep an eye on the plugs over the long term.
