sorry thats what i ment to say that he made a lot more torque earlier! yeah thats a big call to call glen one of the best tuners in perth! i kinda beg to differ! i suppose if u have heard they are the best at the end of the day its your car and money! im just goin on my personal exsperience sorry....

I'd put a 10psi spring into the gate and see how that performs as i dont really think the gates position is your prob... Kyle wouldnt make a manifold with a poorly positioned gate.
If your happy with it thats all that matters... I bet your loving it hey |

How have you got it tapped into the turbine housing?? I woundn't mind seeing a picture of that...

this is the best pic i have. its when i first put the setup together.

AND you say, youve done nothing and it happens to be working 100% FINE?? oh, check your balancer, if you dont have 3 tdc marks, then id bet they didnt check timing on all cylinders with the boost controler, when i set it up for 190kpa the boost controler becomes nosiy untill u get to about 210kpa. ok ok i will check all the timing again this weekend.

ok, but does it stay flat at 210kpa?? see, the point is, it doesnt necesarily have to match that number initially, like the 190 and 210, what you have to do is tune it for the most flat boost curve you can, and then once its controlling properly, you can put the kpa diffeence between setpoint and actual into the boost offset table. like you would put a 20kpa offset in the table.

There is nothing wrong with the positioning of that wastegate from the turbine. It is the best place considering the way everthing is setup. I take it that the turbine is a single entry unit. Even if it were a split pulse it would not be the cause of your boost problem.
The problem lies elsewhere.

The problem lies elsewhere. the exuast housing is split pulse!! were else do u recon there could be a problem??? hows ur ed going??? hay does anyone know how much boost psi the standard valve springs are good for??? heres a pic of wat the engine bay looks like now! this pic was taken with my moblie, not bad quality ay!!!

Wow this thread has heaps of info, I just read all 9 pages in one hit. You've got it looking good now mate, wish I had that setup under my hood.

hey fritzz, i cant beleive i havent heard of anyone else complain of overboosting before, but now, theres 2-3 of us at the same time, chasing the same problem..... all with different wastegate setups etc

yeh me, u and delta. but delta is bad hes getting somthing like 28psi i think. na i havent had a chance to check the timing, but there is marks on the flywheel so hyperdrive must of checked it, but there isnt any trims modifid in the ecu.
