My stock vs stage 2 Bootmod3 Dyno numbers

DailyDownshift · 07-20-2021, 12:44 AM

So I recently started my modding journey on the OG M2. I dyno'd the car completely stock before any mods so that I could see the gains for myself once finished with all modding. I dyno'd the car both times on a dynocom at the same shop with the same 94 petro fuel, temps were similar on both days (23-25 degrees celsius).

List of performance mods
- Wagner tuning 300cpsi sport cat
- VRSF charge pipe
- VRSF 5.5'' inter cooler
- Stage 2 93 octane OTS map bootmod3
- Thor flasher, GTS for every option (probably doesn't affect numbers)

Here's my burning question: Does either dyno session seem accurate based on what you guys have seen on this forum and online in other places? My stock dyno runs seem VERY high and so I don't know how to feel about my tuned numbers as those could also be inflated. I'm thinking about getting on a wait list for a dynojet to compare the numbers coming from the dynocom.

Actual number is really irrelevant unless there's another car from that dyno to compare to. What's more important, and impressive, is the 50whp peak gain from stock to stage 2.

+44 whp and +39 tq, seems normal to me? But yeah, stock numbers are a bit high?

Ya stock numbers seem high which is why I'm also worried that the tuned numbers are also high. Who knows

Very true, I also like how much better the torque curve looks.

The deltas are what matter, but Dynocom’s generally read higher than Dynojet or Mustang dynos.

This.
Do you have an overlay available?

EDWYER · 07-22-2021, 12:22 PM

Hmm like to see what you do on dynojet.

I didn't get one from the shop but I'll ask if it's possible to get them overlayed somehow.

Definitely going to take it to a dynojet at some point this summer just to see how accurate the dynocom was. Will update the thread once I do it.
