Didn't Evolve have that light blueish T5 in Speed and Sound a couple of years ago? I'm sure they did...
You can't go wrong with Marquee specialist tuners!
But if a Ford ST can handle 250kw DAILY then no probs why yours can't go 190...go for it, may I ask who will do the tuning and the price?

The ST owners forum has quite a few tales of unreliable modded ST's
+1 on which company/tuner is doing it
GIAC and FRC come to mind when you consider a reliable company to do the remap
Hi Dolby,
Just some things you really need to take into consideration. Coming from the Subaru tuning scene.... (so this comes from a subaru tuning point of view, gone though this twice)
Ask the tuner what the fuel requirement will be for this setup. In my experience, you'll possibly need an octane booster of sorts. Getting those performance figures out of 95 RON is possibly on the risky side. (Possibly not, I don't know the volvo stuff).
Usually when remapping a turbo car, its sometimes a good idea to also change the exhaust system, especially the 'down pipe'. Essentially, removing all catalytic converters, they are very restrictive. Just ask the dude what about the exhaust system ? In my humble opinion, upping the boost without increasing the engine's ability to flow air (ie less restrictive exhaust), is stressing the engine a lot more (read exhaust gas temperature...read...nah nevermind...just gonna make u paranoid). Apart from the performance benefit, you'll also love the responsiveness of the car with the less restriction....turbo will spool up a lot faster and sooner...you'll love it!
Some other stuff (to add to what bboy already said)
- Ask the guy if you don't need a stronger fuel pump.
- If not, ask the guy how far the injectors will be pushed (from a duty cycle point of view). Pushing injectors too far (so that you can get more fuel for the more air your pushing in), can overheat them and kaboom engine (lean condition leading to detonation) Best practice reckons not more than 95%.
- Ask the dude what the target air/fuel ratio will be when on boost. Best practice is < 12:1. Typical is 11.2:1, safe is < 11:1
Now, some tuners might not like to answer you on some of those as they see it as 'propriety information'. If the dude answers you, then you know you're dealing with a pro. He will probably appreciate it when you ask those questions.
Pushing your turbo to 1.2 BAR is fine (even on the WRX subaru's). However do take note that your turbo is working a lot harder now (what...50% more?) and this will shorten the life span of it. You will probably note with this dude's tune that you will hit 1.2 BAR boost and it will quickly taper off to something like 0.6bar at redline. All depends on the type of turbo.
Apart from all my blabbing above, the most most most important bit to modding your car is: FUEL FUEL FUEL.
Drive it with proper fuel and it will last. As long as there's no know/detonation, it should be just fine (assuming the tuner knows his stuff ofcourse). Proper fuel = high octane fuel, e.g. > 95 RON.
Another thing to remember: your minimum fuel requirement might be 95, when traveling you might not get 95 at fuel stations which will place you in a risky situation. Been there, done it all
Please ask if you need more info, I might b able to help.
On the subject of fuel, which fuel brand is better? I've read 95 octane in this country is not 95 but more like 91. Is this true for all fuel stations, who imports fuel, and who gets it from Sasol?
Just to clarify the 98 Octane I referred to is the EU 98 Octane (US 93 Octane) version. So if we have RON 95, what is its equivalent in Europe?
All brands get petrol/feul from SASOL depot - supplies 20somthing % of the country's feul supply. You have others but SASOL is biggest. The thing is this, as stated by people working there and actually doing the deliveries...
All unleaded and LRP and 95 and 93 feul is the same when it gets dumped into the tankers...Sasol will add its blen, Caltex will add aparent techron, Shell will add aparent V Power etc etc...this is added afterwards by said brand...
EU 98 Octane would be 98 RON in SA
Just the yanks that like to be otherwise.
