I put Vance Hines true duals, full sac slip ons,  just had bike dyno tuned , results  92 hp   and 109 rear wheel tq, based on what I've done does this hp and tq sound about right.  Please advise  thanks

That's about where my SERG was with a stage 1 and decatting.  It would help to know the base numbers.   Enjoy!

Ah, True duals............

That's fairly typical numbers for what you've done.  You might have gotten a tad more with the X pipe, but if you're happy with the looks of the true dual headpipes, who cares?   It might make 2HP and 2TQ better, but you'd never know it.

The main thing is how does it run?  Numbers don't mean chit as long as it's running well and has good drivability.

Yeah, true duals are a mis conception on performance. It will make more hp and torque with a 2 into 1 any day of the week. Tru duals do sound better.....but give up on performance.

Sounds fairly typical to me for a stage 1 mod.  If you have the dyno chart, post it here so we can see the actual curves and test conditions/correction factor.

Peak numbers when taken by themselves can be very misleading.  Each DynoJet is different, and each different dyno operator can affect the numbers as well.  All we can really tell you is that your numbers are within the normal range most folks have reported for just pipes and a tune.  The most important thing is does it run well and put a grin on your face?
