NIStune is around $1,100 supplied installed and dyno tuned. Power fc is 950 (as u say) then tuning costs on top

Does seem a little down on mph fr 450kw. But good work

Depends how fast u were Changing gears Sime. Then gear ratio's come into play. Have u weighed ur car?

No shuffle at all Paul. And Scott ur not allowed to use low boost at the drags

Perfect. Yes theres still more in it. I would prefer to see u enjoy it then push to the limits

I reckon stick to modifying the airbox for now. The underside can be opened a fair bit. But u need to get cool air to the box aswell

Haha Deano. Ur 32 psi was unintentional

Ohh and we actually opened the airbox at 403kw as even that was a push.

The car fought all the way to the end but was worth it He should run 130mph, i ran 131mph with 402kw. Time to test those skills out mate. Let Me know and i will meet u at wsid

470k ohm resistor? Just double checking. Also try 2 new resistors as i have seen them not work the first time

Has it always happened or only just started?

Yes definately not fun. Its definately easier with the engine out haha

Its a veryfun job to do on RB26's. willtake atkeast 3hours to get off, then cleaning of old gaskets and replacing hoses etc. then atleast 3hours to get back on. DO NOT CLEAN IN AND AROUND THE THROTTLE BODY BUTTERFLIES!!!

Some rb20's have a pressure referenced dampner too

Yes sounds like the inlet gasket is blown. Its pretty common to happen as the gasket gets old. I normally replace the inlet and throttle gaskets with a set of metal nitto gaskets. Also check all the hoses under the plenum as they may need replacing while the plenum is out

If u have changed the intake pipe setup for the afm position this can happen. It may be reversion through the afm. What ecu and afm?

Explain the boost creep.

Same level, but if ucheck when its warm make sure u waited atleast 30seconds or so for the pil to drain back down after turning engine off

Do u have a boost gauge with it? If its the one im thinking its just a simple turn up and turn down?

They are a great ecu for the price. Also constantly upgrading and expanding

How do u have the afm? Have u checked for leaks

Sounds like it could be a blown intake gasket on that cylinder. Get some brake cleaner or wd40 etc and while the car is idling spray around cylinder 5 inlet, throttle gasket and injector oring etc. see if the idle changes

By raising to 1.500 u have added fuel. Did this fix the issue? Test fuel pressure and get the tune checked. Check for vacuum/airleaks too

Bugger about the compression but could see that coming. Did they try a wet test to see if its pistons etc? Where are u located?
