C30 T5 custom remap
 

So I own a 2008 c30 t5 (b5254t7 I believe) and have been slowly adding bits to it to get it ready for a map over the last year or so. The time has finally come to get it mapped but I am struggling as to where to take it. I've seen plenty of places offering generic maps but I really want to avoid this route and get a custom rolling road map as the car is modified and I want to safely get as much power out of the engine. The only decent option I have seen so far is dreamscience. Has anyone had any experience with these? I see they do a lot with the st's and they seem to know their stuff but I live in a stoke so they are a few hours away and I'm just weighing up my options at the moment.

Current mods I have at the moment:

K&N typhoon induction with hardpipe kit
AS performance alloy inlet plenum
AS ported and polished inlet manifold
Forge recirc valve
Forge wastegate actuator
Elevate tcv
Do88 intercooler with hardpipe kit
Jetex cat back
AP coilovers
Elevate torque mount
(currently running about.8 bar of boost)

If anyone has experience with mapping this engine what other mods would you recommend? I.e. Focus RS injectors, uprated fuel pump etc.

Also when I get the car mapped I will be fitting a 3" downpipe and a 2.75" decat, however, the cat back is 2.5". Does anyone know if this will cause flow problems or anything? (I cant find any smaller diameter downpipes)

Any information or help anyone can provided will be greatly appreciated!

I actually work in Hull!

My advice is to go to Shark in Mansfield, they have a reputation for their Volvo mapping, particularly the T5 engine.
My D5 will be going there at some point for a Stage 1 off the shelf OBD map fairly soon.
There is also OBD maps for the T5 up to Stage 3 - 300BHP 500Nm.

Contact Shark they quoted me £314 today for a stage 1 that was with 10% discount fir being a forum member, they are in Mansfield and have a dyno as well.

Interested to hear more about OBD maps for T5, can they be applied by the owner with/without special tool ?

When Shark did my S40 T5, I got sent a soft loader ODB11 thing (paid £200 deposit, was your choice wither to return the soft loader and get the deposit back, or keep the soft loader and lose the deposit). the process was plug the soft loader it, it read the ECU and got all the settings, then send this to Shark, they then sent back a remap file, you then used the soft loader to write the map to the car. They were brilliant with me first map was very savage and made the car a beat, but it wasn't very driveable, so they got the map back again, tweaked it, and it was much much better.

The benefit of keeping the soft loader is that it held both maps, so you could change between standard, and remap in about 5 mins, which is always useful.

I have been looking at remaps myself recently, however I have the D5 engine in my C30. Have you heard of Celtic Tuning? Someone mentioned them to me so I looked them up on google and they claim their map will take my car from 180bhp to 235bhp and the torque from 291lb/ft to 351lb/ft. I had to email them for a quote and they came back with a price of £295 and they said they could come to my house or work to install it for me. I thought the price was ok, my concern is the leap in BHP, it just seems so high when you consider Shark Performance's remap goes up to 215 and they specialise in Vovlo's.

Celtic Tuning
 

I used them, Celtic Tuning, to remap my 2006 C70 from 220 to 260 BHP. Made a tremendous difference to the car and did not affect the fuel economy or the insurance premium

Shark performance
 

For what it's worth I can vouch for Shark Performance as mentioned in some of the other replies.

I know at least 4 people that have had re-maps from Shark, no complaints from any of them. Great people, good personal service, well respected :thumbs_up:
