Recently I had my car tuned at a reputable tuner in Sydney my car consist of.

2005 ba

Atomic valve springs,

walbro pump,

x-force s/steel dump + cat,

removed middle muffler,

avo cooler,

rapid intake,

60lbs injectors

Now the car is running 15psi consistently no spiking or anything.

Final power when tuned was 306rwkw I paid $770 for the tune! & $770 to install the springs!

I now take it for a check up at another shop and get told its pulling 259rwkw with alright afrs and low timing!!!! WTF

Bid difference from initial dyno!

Now I don't want to start a sh*t fight I know dynos are a tunning tool and quarter mile is where the numbers come out but really such a difference. Both dynos were dyno dynamics!

I feel a bit ripped off! Also 15psi with those mods & only 259rwkw

Please please anyone voice your opinion

259@15psi doesn't sound right.

Did they check for leaks etc as well?

Nah! If anything it feels like it has more power then before! Car runs great.

What could leak causing loss I power but still drive fine?

Post up the dyno sheets. Edit out the workshop names if you want to avoid the sh*t fight..

Something is not right. All been equal you wouldn't expect that big of a difference, maybe 10-15kw but

over 40?

Surely you'd feel the difference between 300+ and 260? If in fact there has been a loss!

Will do!

I will scan the dyno sheets and upload this arvo!

First dyno with 306rwkw only has the power and trouqe curve!

Second dyno has power vs boost!

Car feels the same but don't know how there is such a huge difference in power between the two dynos!

All I could think was $4000 spent for 259rwkw & 15psi :(

Another option is go back to original workshop, show them the latest results. A good workshop would surely want to investigate and check their tune for themselves.

Only problem is that I'm 6 hours away!

Sounds like your happy with how the car drives , so who cares about numbers.

Haha I thought this might be an SA thread reading the title on my phone. Does sound wierd but.

Hahahaha nah nsw, might just have to wait till I quarter mile it! I get 0-100 in 5.3sec and hit roughly 175klm in 400m!
