Just been getting some tuning done to FG XR6 Ute (auto) 2011 with euro4 spec. Fitted 968's and got some good street power now. When on the dyno trying to get a clean power run in it would change down even if in manual tiptronic and made it impossible to trace a good line all the way through. Just spin up the tyres on the dyno even tied down hard.

Also, is there some kind of torque limiting control on 1st and 2nd gear that reduces boost until it hits 3rd gear? couldn't find any way of getting in to the program to change this?

Any clues would be good,

Cheers.

Who's tuning it? I'd be a bit worried if they didn't know.. And 968's probably to small as well.

Short answer would be yes.

968's are the best option for power levels up to low 300rwkw's IMO.

Very odd that it won't hold gear.

42's really? Wouldn't 60's for roughly the same price be better so if you choose the go for more power later on you don't have to buy another set of injectors?

That's why I said low 300rwkw's.

If you want more power then you'll need bigger as you mentioned.

You need to find a tuner who knows what's going on

You don't press the throttle through the firewall firstly

Secondly I have seen 2500hp successfully run up on a chasis dyno 280rwkw isn't going to smoke the bags unless you have plastic tyres

You put it in 4th manual mode, you press the throttle down till you feel the notch = 100% throttle no kickdown.... Job done

Thanks guys for your feedback - put 42lb injectors in because they were free of charge (somebody gave me them) The guy who is doing my tuning does mainly Jap tuning and is very succesful at this.

Using ECUtec software I think? and this is the first time he has seen the goings on in the Ford ECU. He's doing the right things and playing it safe, but learning at the same time.

Living where I do, I cant just drive up the road and find a Ford performance tuner that has done 200 tunes and knows the ins and outs - so really just trying to read between the lines, as there is so many different views.

Appreciate your views though guys, we'll just keep plugging away. Car is going great I might add pulls like a southbound coal train...except terminal velocity is somwhat higher!!

Will keep asking dumb questions till I'm no longer dumb - Cheers, Luke.

Just while I am here, also - what would you guys determine to be premium fluids for the auto when putting more than standard power through it?

Are there some high performance synthetic oils that can be used to good effect in the ZF 6sp. auto? (still factory oil at the moment)

What is considered the best engine oil (using Mobil 1 0-40 at the mo) and axle oil (currently still factory), for the extra loading and heat etc?

Is it worth putting in a lower temp opening thermostat etc?

Cheers,

Luke.
