Lack Of Power

[our12]

Hi.

Maybe your original tune is not right. Perhaps your ignition map is not correct. I have seen 252awhp with a dyno sheet showing afrs as they should be but the car was capable of more. Taken 2 days later to another tuner here in brisbane- 10 minutes correcting ignition map only and 308awhp as it should have been.

since the motor is "fresh" is this just your safe run in tune ?

I think its just a safe tune.. but not to sure.....

not sure who else does VIPEC computers in bris???

any sugestions... i have another 5000klm before was gonna go all out with the tune

just to clear a few things up..

my set up has had it fair share of issues,

t04z on stock rb26 i was only making 315kw on 25pound. replaced engine to my old built one from my dr30, went to 376kw. the inly differance was pon cams and a very light port.

so.. from my experance, and excluding all the 450kw freaks out there, cams netted me a gain of 60kw atw... and it was still not making as much as id hoped. but looking at my graph it falls over up top sugesting a spring upgrade is a good idea.

thanks T04GTR, ive got the Hks Step 2 valve springs in it and am looking at hks 265 step 2 cams.... ive got a better manifold, bigger dump is under construction, the only other thing is to grab a good waste gate... with that setup we and 25psi we should be looking at about your power, was hoping for 400kw atw but id be happy with what your getting.. thanks everyone for all your help... will keep you all updated with the results.....

Wait wait wait, whoa whoa whoa

after all the suggestions and people trying to offer experience and help, now you say it's a run in tune?

Who cares what power it makes during run in, even 100kw is enough.

Mine on run in made something like 150kw atw, of course it was a safe tune, ran stuff all boost and wasn't rich to make sure the cylinders didn't get too much fuel on the sides.

Ran in and tuned, 455kw atw.

Morale of the story, if this is a run in tune and you don't really know what's going on, ring the tuner, ask exactly what the tune is for, and if it is just for run in, get the k's on it quickly then go back.

In the meantime, don't stress.

Its already run in, by the time the run in tune is done, its already run in, just a way for tuners to make money out of customers

^ Exactly

hay guys me again.

ive got someone lined up for a swap for a gt35/40 for my t04z... should pull my response down a little.....

thanks for all the help...

True but to be fair many engines are not built by the tuner.

When i build my own customers engines i will run in and tune in one dyno session, BUT if it was built by the owner or by someone else i have no previous experience with i will often do a decent run in tune say 80 % of projected peak then ask the customer to drive the car for 2000-5000km to heat cycle everything (joiners, gaskets etc) to iron out any potential issues then come back and charge by the hour for the final 20%. I figure 5000km will show up any potential issues.
