Thats the most generous dyno I have ever seen!!!! I cant see you getting that without Longtubes and thats even high if you had Longtubes... When I was stock "M6" I dynod 326 WHP 335 WTQ which is above average on a 04 GTO... With Longtubes, O/R mids, CAI, SLP LM1, Magnaflow X and Dyno Tune I put out 349 WHP 354 WTQ.... So IDK, I Now have a TSP 228R cam 228/228 588/588 112 LSA with a UD pulley and Ported TB... No dyno numbers yet for the new setup but Im thinking 390 WHP maybe more IDK... But for your mods I cant see you getting 355 WHP... I pretty sure the dyno said that but thats one hell of a generous dyno...

Always wondered how a dyno dynamics compared to a dynojet. I guess now I know, haha. Get it to the track and see how it does!

From what i have seen mustang dynos read about 15% lower than a dyno jet, the dyno dynamics read 15% higher than a dynojet. Thats why dyno number mean **** these days lol.

Anyways, numbers look good, but now it's time to take it to the track and see how she does.

yeah i agree the figures look a little rich, and im yet to go on the strip.

funny thing is, i know someone on my street with a 911 carrera 4 s (380bhp) happend to 'see' him on the motorway, from 70-150 i pulled 8 car lengths, its confusing me.

the car has had work done to it before, the rockers being the only mod i know off, im still trying to find out more history.

even if the dyno figures are lying.....
bottom line, the tunes made it drive much better, and better mpg too!
