which cars gain the most when remapped?

[Lefty]

C6 RS6 goes from 572bhp to over 700 (dyno proven) with "just" a map!

Should CO2 figures be adjusted for tyres as well?

they are!

look at the same car's CO2 numbers if it's offered with different wheels/tyres, the figures are different.

See my reply above/below.

Merc 220cdi are identical to the 250cdi apart from the map so 170->260bhp is possible. As far as I can tell anyway.

The W204 c250cdi are twin turbo against 220cdi single turbo. Fairly sure it's the same on the latest generation as well.

ETA, it appears there's been a fair amount of discussion on the veracity of my statement elsewhere on PH in the past. Sorry I wasn't looking to reopen old wounds

Yep.. Looks like there's been big debates in the past.

From what I've gathered it seems to be the 220 has smaller injectors so will actually go from 170 to 210. Credit to the chap who's already posted to that effect.

I've bought a DTUK tuning box for my Golf R...won't be as much gain as a remap but should add 30-50bhp to the already healthy 300bhp by all accounts from the independent reviews and tests I've seen.

The DTUK website quotes an optimistic 375bhp (standard 300bhp) and 527Nm (standard 380Nm).

Given how much fun I'm having in this little car already (more than I had in my remapped 335i and 911) an extra bit of midrange will be awesome.

Are those gains possible with any 2.0 TFSI engine?

Pretty much.

I just sold a 2.0T A4 with an AMD map on it, rolling road was 196hp stock and 258bhp after map, that was the basic map too.

My better half's V70 2.4T petrol is BSR remapped. I did it about 9 years ago and it still runs as sweet as ever.
The figures BSR quote are 252bhp & 400ft/lb. It was originally 200bhp.
The difference on the first full blast run up our drive was amazing. I was truly gobsmacked at the difference in power.

I'd love to get my Conti' GT remapped but the cost is stupidly expensive. It would no doubt be fun though.

Interesting - my better half has the 2.5T and you're quoting the same figures as hers gets (think it starts off at 209bhp mind) - it's a beautiful bit of extra oomph though, and hustled right with a manual the 2.5T in stock tune is no slouch.

Debaser said:

Doesn't it depend how long you want the powertrain to last?

Very true. The clutch on my remapped Octavia Vrs has only lasted 118000 miles since the remap.

[paulmakin]

the B series Saabs won't go to 300 with just the downpipe and map. you will need at least a TD04 and better intercooling. maybe injectors depending on the base engine, a 3 bar map sensor and a 3.5 bar fpr

viggen clutch although you might get away with a new standard jobby if you're careful with the torque - it's capped in 1st and 2nd for a good reason. diff might start to struggle as well after this point

then you plug it into T5 or T7 suite and adjust the "boost requested" box in the wizard and away you go.

remap figures should always be taken with a pinch of salt.

[gbruckner]

The F21 114i goes from 102 PS (180 Nm) to 210 PS (280 Nm).

Over 100% with just a remap (zero hardware modifications).

[Pdelamare]

Approx an additional 110hp extra per before and after dyno runs from my 5.5TT E63.

More impressively an additional 200lbs/ft torque!

The output figures your friend were quoting are the 350CDi with the 3 litre V6 engine, not the 220/250CDi.

My SLK 250 CDI is stated as having 201 BHP, how does this go to 260 BHP?

Sounds good, but not sure the traction control would like it.

[gizlaroc]

The C200 W205 petrol, is 180bhp standard, same car, same injectors etc. as the C250 petrol, just detuned. Both will map to 260bhp.

Would be full retard to do so thou. Maybe the turbos can get there but I bet the engine components won't cope.

[Corbeliere]

At the end of the day, it's what the 0-60 and 1/4 mile time improvement is that matters. The figures mean nothing really, especially if you don't know how to get the power down properly.
I say that as an ex drag racer.
As for my other half's V70, it's a bit too powerful off the mark and easily spins the wheels. That's a problem with most FWD's though.
The Conti GT with it's 4WD, now that's a totally different story!! YeeHaaaaa!!!!!!!!!!!!!

What makes you say that? Do you have first hand experience?

The 2012+ F20 114i has a software detuned N13B16 engine, same as the one in the Mini Cooper S, 116i, 118i, 316i and 320i ed.

It's an engine was sold as a 170 PS/250 Nm (118i/320i ed) version with the same internals, turbo, cooling. etc. BMW detuned it via software because it was cheaper for them to reuse the same parts. You're really "only" running it 40 PS / 30 Nm over the spec.

IMO these cars are real bargains at the moment. Cheap as chips, RWD and enough power to hang with a new GTI.

[Tyler Durden]

That's the kind of thing I was hoping to find out.

Nice one.

VW T5 gains are pretty impressive.

84bhp to 138bhp- over 60% more power.

Yep then the van sts itself when ever it gets used.

[Steve93]

My Saab 93 sport HOT went from 200 to 280bhp with a stage 2 remap, and my 9000 2.0 ecopower went from 150 to 240bhp with a stage 2 also.
