Now I know my car is sort of on the build period of when they received typhoon internals etc.My car is getting dynoed today and the tuner has told me he's only expecting 270-280rwkw because that's all the standard valve springs can handle.. I have read every possible google search relating to this and there seem to be people out there with BA models even with less mods getting closer or over 300rwkw??Surely the standard valve springs can get it to 300, otherwise this tune feels like a complete waste of time and money considering my car already feels like its got around 250rwkw easy just with my below mods!Thoughts??My car mods up until this tune are:*4" dump into 3" hi flow cat*Full Growler kit CAI*50% bigger intercooler*Walbro fuel pump*60 lb injectors*Brand new spark plugs*New turbo actuator* And full tank BP Ultimate just to top it offCheers, Josh.

Besides running those mods without a tune is asking for trouble Link to comment Share on other sites More sharing options...

As your tuner said, 270-280. You never really know with the factory valve springs. You'll basically have to wait till it's on the dyno but I'd rather just pay for one tune so I did them before just in case. Link to comment Share on other sites More sharing options...

I'll post up what it gets this arvo. I'm still hopeful of a nice suprise when they call me!Thanks guys Link to comment Share on other sites More sharing options...

Much nicer to drive and a lot more midrange generally too. Link to comment Share on other sites More sharing options...

The "best" way is mph trap speed at the 1/4 from all I've read. Link to comment Share on other sites More sharing options...

But all 200 spots were full just after 6:30pm.. Tuner shafted me today and now it's dyno run is pushed back until tomorrow. Nothing worse than waiting!!

I dont think the springs were going to be much of an issue yet, but won't really know until I push for some more down the track. Link to comment Share on other sites More sharing options...

But now they're floating. Link to comment Share on other sites More sharing options...
