I Re Dynoed My Car By A Dyno Jet 343 Hp

I'm sorry that I made a thread but I I've never seen under 300 max HP ??? I have a 2008 bmw m3 with just a Meisterschaft with the sr pipe.. I just dynoed it to see how much I'd gain after a tune.. My car was dynoed on a mustang dyno I was told that other dynos would of read 350.. Is this normal to you guys? They did a 5th gear pull..

There's a list of about 30 Mustang dyno results. You can see how yours stacks up to these.

Well they dynoed it the first time 4th and it was a lil lower so then they dynoed the last 3pulls at 5th because they never dynoed an m3 they usually dyno jap cars.. Well anyway I'm worried there might be an issue with my car bc it seem quite low I was honestly expecting 340 at least? Thanks for the input guys...

What tune do you have? ESS and Evolve will both update you to 240E.

Let me get this straight... You are swapping out parts designed by some of the top engineers in the world because some guys sponsored by a company told you it's "better??" But when you ask the same guy about tracking, "oh no, I have a kid now" or "I just detailed my car." or "i just got new tires."

No Chris I have 19s but I'm not talking about a 10whp loss more like 50 whp!! You think spark plugs could be the issue? Might be original, the car has 25k mi

No tune or update yet I planing on doing the bpm sport tune?

You need to get your software updated along with spark plugs. Search for 240e on the forum. This might answer your question.

No. 30k - 37K miles. Manual says 37k.

Either drive or ride with a fellow M3 person...see if you can tell a difference. at 280 whp, you should be able to.

Post the graph with the correction factor.
A dyno can give wild readings if the SAE CF is very negative and over correcting.

Why does everyone think upgrading the software will restore power? This is a myth.
