When your setting up the tunes on the T do you usually run so much boost low down in the rev range as would of thought this would put extreme load on the transmission/Diff etc.I am sure you could get the exactly the same power output [305rwkw] with a more progressive power curve maybe.In a ute the thing would have to loose traction everytime when under power?.When cruiseing down the expressway say at 115kmph the boost would be nearlly on 14-16 psi all the time/Please correct me if I am wrong.

Do you find it a better way of tuning these things for say quicker 1/4 mile times or drivability.

Please note I am just asking a question as you are tuning these things everyday and doing a good job by the looks of it but why so much power low down?.

Over boosting down low can cause damage yes, Engine, Trans, Diff, of course, Its always something you need to mindfull off when tuning. If the customer wants that low down power you do what you can without trying to break things. None wants a customer with a broken diff, trans or even worse an engine.

Both cars that have had gear box troubles that I have tunes one had done 80000 kms and was stuff before we started and the one that belongs to this graph was already slipping when I tuned it, My Wifes XR6T had been driven to Melbourne and back and done drag racing and of course daily duties to the school yard for the kids.

Like I said noone wants broken bits. On my own car well that's a different story, I push it.. I push it hard.. I want to find the point where it cant take anymore so I know how hard you really can push.

I

am sure you could get the exactly the same power output [305rwkw] with a more progressive power curve maybe.

If overall Boost and Timing are the same then yes the peak figure should be the same.

When cruiseing down the expressway say at 115kmph the boost would be nearlly on 14-16 psi all the time/Please correct me if I am wrong.

In correct, when you are criusing you will be loucky to see any boost, unless your towing or going up a hill.. at criuse you wont.

Do you find it a better way of tuning these things for say quicker 1/4 mile times or drivability.

Problem we have is Ford gave us great engines but not so good of a car in thw weight department. When hooked up correctly the low down power and torque will make for a very fast car. None wants to have to use stoopid gear ratios or huge converter speeds as a result of a heavy car with no low down pull... again something everyone needs to be mindful off so they dont break things with Too mush power down low. With billet rods ect it isnt as much a problem.

Please note I am just asking a question as you are tuning these things everyday and doing a good job by the looks of it but why so much power  low down?.

When questions are asked like this noone in there right mind would take offence or get fired up. Hope ive helped you in some ways, Keep em comming if you need any more answers ill do my best to help u.

Thank you for the informative reply.

When you are tuning these cars do you say give your customers the option of a tune like on the graph with power curves like on the graph or say a more progressive power output.When a car like the ute is tuned that way would you consider it to be a quicker in day to day driving or 1/4 mile work than say a car with the same power up top but less power down low?.

I just could imagine that ute when as I suggested before on the expressway doing 2200rpm running little boost or not under load then putting your foot down to overtake and having 16psi would be abit of a handfull?.

When you have set up your F6 how have you set your tune to achieve 400rwkw.You have probley posted a graph before but if not can you post one up or give me a link.Do you bring it on heaps down low as well.

Taa mate.

Now that's impressive mate.With that amount of power mate do you think your car could be slower over the 1/4 due to no traction?.

From reading other peoples stories with cars like yours have you snapped any drive shafts yet or I should say when do you think you will snap them?.

Very impressive.Taa.

ive done 7000 kms , no drive shaft issues. I havent ever broken a drive shaft. Im hoping I will get into the 11's with this power on street rubber, time will tell. Hopefully have time to head there in the next couple of weeks.

hey guys just so it's clear about the trans in m car....the car has almost done 60000kms and was modified at 30000k's. the trans started to slip when engaging second gear when it got to around 225rwkw. my car is a july 03 model that was too early to get the kevlar clutch packs and bands. i had a mod done to the trans at about 40000km's and the car's done aprox 20 runs down the strip at kwinana and two 5000km round trips (one was to coral bay top spot ) as well as the normall thrashing around day to day stuff. they idea behind the valvebody mod was to prolong the life of the trans. it was never a case of if the trans let go it was always a case of when...so i wasnt at all suprissed when it started to play up the the new tune....

cant wait to get it rebuilt and beefed up and give it a good run down the plex and see how fast it goes!!
