Low dyno numbers, would like some opinions
Hi everyone I recently got my 370 uprev tuned and was quite dissapointed at the numbers(will post dyno sheet in a bit). My 370 is N/A with Stillen catback exhaust, Stillen gen3 cai, and Motordyne art pipes. With these mods I expected to definitely be over the 300 whp mark. But with the tune I ended up at 280 whp, and before the tune it was only at 264. I cant imagine why the number would be so low. Tuning was done on a dynapack dyno.

Jtune performance was the shop that tuned my car and they used the uprev software to tune it. Pretty sure it wasnt the shop though considering I did get 14 whp from the tune.

It was a dynapack which reads high, or low, and everything in between.

16 hp from a tune seems pretty good whats the problem? Go somewhere else and have a dyno run done if you really care about having a sheet with a bigger number on it. Every single dyno will read differently. Some read lower or higher than others. Some unscrupulous shop owners have even been known to change correction factors so their dynos read higher so more people will come their (help inflate their egos I guess). The most important thing is you got an apples to apples comparison before and after on the same dyno.
If you are just worried about if being something wrong with the car (which I doubt), you'll have to get it dynoed elsewhere. |

That torque curve is pretty ugly, I'd agree with going to get another dynode elsewhere
