Help!! torque/power delivery down

[Hurdy]

Hi all,

I recently went on a Rolling road day and found out that my car is down on power and torque. I'm hoping it is nothing major or awkward to fix. I've checked for boost leaks etc, with no joy. VAGCOM looks like the timing maybe out a little but nothing that would lose me around 20bhp and 60lbft.

Output is 315bhp and 296lbft and other ED30's made 275lbft with just a milltek and no remap!!

Remapped only cars were making 305+bhp and 350lbft

One car with DSG like mine and just a map and Milltek TBE made 315bhp and 357lbft

My car has Carbonio, fuel pump, custom map (not generic type), Forge DV, Milltek TBE and Forge Twintercooler.

The same company that did my map did an S3 recently (basically same engine and mods) which made 348bhp and over 360lbft.

HEEELLLLPPPPPP!!!!

Are you sure you are no confusing Nm with lb/ft figures? If those are indeed all lb/ft then you are quoting some pretty high torque figures there.

Standard car is 221lb/ft, approx 300Nm, conversion is roughly 1.36

Definitely lbft

Look at the link below for the RR results on Awesomes website and you can see differences.

Hi

You are correct. But you are comparing remaps by different companies.

Even maps from the same company will often be tailored to different customer requirements. Every tuner has their own opinions to what is a safe reliable limit.

Your map has quite a constant torque curve, which means the power builds as the revs increase, wheras the other one you mention has a much higher peak torque at 2800 ish, which then drops off as the revs build, giving him a much flatter power curve. He has more low down grunt than you, but the same peak power.

Yours is a safer remap, remember that it is torque that will break clutches and gearboxes, but his will be a faster car, as it produces more power all the way through the rev band.

As for getting more power, ultimately it is the amount of fuel injected into the cylinders that determines the power output, and this is determined by the fuel map in the ecu.

Unless there is insufficent air getting forced into the cylinder for the amount of fuel being injected then mods to the induction system will not give you any more power. The other car you mention proves that.

Short answer: if you want more power you will need another remap.

I'm booked back in on Friday as the tuner says that something is wrong and that I should be getting more bhp and torque. I'm hoping it is something simple
