$220, that was a touch up on an existing tune.

Sweet. Now that I got my fueling and CAS fixed, I wanna get the Stagea on the rollers to get back those lost ponies.

Did a compression check a while ago and thankfully no compression loss or blown rings etc. Thankful that I babied the stag around when I knew it wasn't running right.

I wanna get to that turbo/dump gasket leak this weekend too.

damo that boost curve looks consistent with the r34 turbo

a really good ebc may fix up the peak & hold boost, or better yet a fully tuneable computer

as it is it isnt a bad tune...

i have a power fc, but a shit boost tee.

ah simple then, save for the power fc boost controller - scour ebay, JPS Trading Ltd is a good trader to search thru

you can see where the boost T isnt cutting the mustard from 80-120kmph

see how a decent boost controller works better ?

edit: the dropping off of boost was from restricted exhaust, much flatter now at the pointy end of the graph

tune of new piggyback ecu on 8th Oct, update then with a 250+ kw tune map

If you still have the factory boost solenoid in line then i expect if you had a your boost graphed then this is what it would look like (This is a mates figure from his 33). How much boost are you running? Is yours an auto or manual because that figure looks a bit low to me (depending on boost). The other thing that would be playing a part in the hole is the VTC timing not being perfect.

still dropping off - but fuelling is the issue here

again, on 8th oct bigger injectors slot in, so will update some graphs for discussion.

Id suggest damo that a better ebc will do the job well. p-fc boost controller.

Where is the dropping off boost shown?

The graph says 10-11psi, when he rang i said around 10.5psi would be fine, and i assume thats what its on, hard to read from factory bar guage. Its a manual.

Its a turbosmart bleed valve, and always has lost boost from 4000ish to redline since it was fitted.

:D This is gonna sound pretty gay. But for some reason Damo, You were in a dream of mine last night. And you drove a VT commodore.

Thats sweet Craig. and by "drove a VT Commodore" i hope you mean "watched you have sex with Megan Fox"

    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car

    • All my Polish car culture insight comes from watching Nightride. So I half expect this to get 1UZ swapped eventually?! Are you going to drive it in winter? I'm always curious how ATTESA would hold up in the snow. There isn't that much opportunity to try it in Australia.
