When the CHIPS are down

Just relaying information from a tunning company. I was sitting next to Mike with his laptop pluged into my car at the time and he was showing me all the alterations you can make to the chip and there are quite a few.

Below is a quote from the tunning box company which makes plug in chips for turbo diesels.

(only the volume and time of injection are altered, never the injection or turbo pressure).

I do agree though that the boost must be increased as well as the fuelling to enable 110bhp, but most of the chips I have seen quote smaller gains of between 15-20bhp. I'll e-mail Mike and find out the before and after boost pressure.

Being greedy then, a decent CHIP plus a Tuning Box would have me in heaven or jail quicker than ever..

As the tuning box is going to intercept information from the new chip and then work it's magic on the new chip's information, this could be very interesting,, I am almost tempted because with my worst fuel consumption so far at 55mpg when driving hard, I haven't got a lot to lose.. things is I am not a speed freak [well not anymore], I just love loads and loads of torque.. and with 258Nm to play with at the moment I would love to see 300Nm.
 
Hmmm...that company produces a box which goes inline with the ECU not a chip. So they use the standard curves but modify quantities. Chips can alter the curves aswell. As Shezlee says, I cant imagine an engine having so much power and torque without increasing compression ie.Turbo boost. Especially considering the fuel savings. Also running the same boost but more fuel means the engine will be over fuelled (or it was running lean in the first place) and lots of fuel sloshing about washes oil off the engine internals etc etc. Mind you I only have experience of petrol engines so what so I know :)

Just had confirmation from a technician at Jabbasports with regards to their 106BHP TDI chip upgrade.

"The power is achieved by an increase in the fueling and a small
increase in boost pressure by 1.5psi!"

Petrol turbos when chipped quite often double their boost, ie my Leon Cupra was running 8-9psi after it was chipped it was running 15psi. Turbo diesels are nearly always running at near max boost and it's the increase in fuelling that provides most of the extra power.

Although the maximum boost is only altered slightly I imagine the chip allows maximum boost to come in sooner so there is a larger spread of grunt than previous. Car manufacturers tend to "blend" the boost in to stop the feeling of Turbo lag. A chipped Turbo tends to have its power/torque come in sooner and stronger because of this.

That would mean that a chipped engine would produce more torque at low revs with the possibility of better fuel consumption with the sacrifice of a more sensitive throttle at low revs.

I don’t want to be an idiot, but is there any general opinion as to which sort of chip to go for? A plug in box which I have been told gives minimum of 15bhp extra with the option of enabling about 7bhp more on top, or chipping and getting about 30bhp. Is that extra 8bhp difference really going to be noticed between the two? I wonder due to the dilemma I’m in as to which to purchase. Or could I buy the plug in box, and then get a company to increase the boost slightly on the turbo to gain that little extra. Amount of gain and point of doing this I wouldn’t have a clue. Am I rambling on a load of nonsense now? Help appreciated.

Get the box and the chip and then tell us what the package is like.. if not get the chip, it makes more sense in the long run, better fuel, 50% increase in BHP 30% increase in torque,, what more can I say.
 
Does anyone have a plug in box? If so what about maybe meeting up and trying the combo of box and chip at some point? Slighlty worried the A2 might go ca-boom after a while though if ran like it constantly!!!! 300Nm would be quality, i wonder if that would make me sit back in my seat when i pulled away?!!
Has anyone changed there air filter for, K&N jobby? I've never used them, do u think it a worthy upgrade or is it more gimmiky boy racer crap?

If you run a chip and a box you are in serious danger of running outside the safe design paramaters of what the engine was designed to do. To get more power you need a bigger turbo, bigger intake, bigger injectors etc.
 
What I really need is a 6th gear as this baby could easily pull some more if it had the extra gear,, not too mention the extra fuel saving,, just imagine 70mph at 1500rpm.. and still have enough torque to pull away clean.
