Hi Guy's
I am new to the forum and just wanted to ask a couple of questions please.

I have just bought a 2006 2lt type uk sti with the Prodrive 301bhp conversion,the car has a large stainless exhaust and a HKS dump valve apart from the 3 pod gauges where the clock used to be its standard.

Now i know fuel consumption and Scoobies don't go together but mine seams very thirsty!

I used to have a 2001 WRX std and i could if i behaved get 30 mpg out of it.

Now i know the sti is more highly tuned but if i run round off boost and change up early i am lucky to get 18-20 mph if i give it some in short bursts i think it does about 10 mpg you can see the gauge moving!!

I have been running on purley super plus unleaded

Questions
1/is the above normal about right?
2/do i have to run on purely super plus or can i alternate between normal and super plus every other fill up.
3/What sort of BHP would this engine be capable of on stock internals and drive train etc and still be reliable?

Thanks

 

1) Yeah about right. Mine does about 180miles to a tank. The dump valve won't be helping fuelling either. Might be worth getting a remap, as this should improve the MPG over the prodrive map.....plus it may not have been mapped for the new exhaust, which it should have been.

2) Yeah, only use Tesco Super or V-Power ideally.

3) I'm going for 400-420 on my internals.


Mine is a 2003 STI running 350bhp at the moment.

 

Hi thanks for the reply
What size tank are on these then,i ask as i havent ran mine below a quarter full.
I have noticed though that it takes about 60 miles to go from full to 3 quarters then drops really quick so the gauge must be a bit un progressive

Thanks

 

I say that is high...you should really gets around 21-22 in town driving (with only 310 bhp ) !!

but thats not so bad...I run a P1 with 2.5 forge conversion and i get around 19-21 mpg
my other car ( BMW e60 M5) only average around 15-18 mpg !!!

 

PPP makes the car run very rich. I had my PPP remapped and MPG has improved considerably

 

Ok who should i be going to for a remap?
I live in East Yorkshire so more local the better,i really want somebody recommended as i don't want any numpty doing it.
Also how much should i expect to pay

Thanks

 

lots abouts, theres TheRacingline in Halifax, Prosport in Stockport, manchester, Andrew Carr in around manchester area as well , I personally use Bob of BR developements in Swinton

pricewise around 500-650

 

He'll already have the ECUtek though won't he?

Jolly Green Monster on here is the guy to use. He will come to you, and map your car for £300 + VAT (if you already have the ECUtek that is)

 

www.remotorsport.co.uk 5 mins off A64 York

Rick sorted my remap as well asother improvements. Absolute dedication to providing top quality service. Bob

 

I went from 17-19 mpg with dump valve, then fitted standard as i was advised on sn (glad i tuck it off) now i get 19-22

 

How do i know if i have the ECUTEK?
And where do i look to check?

Thanks guy's for the advise.

 

I don't think ppp has a full ecutek licence so you need to pay full amount. Might be best to get a spare ecu and get that one done, can always sell the ppp one on then to help with the cost. Or even just keep it so you can put back to std come selling time

 

I know someone selling an ecutek ECU very soon which was mapped at Powerstation, so if you take it back there, it may not cost as much to get it remapped.
