Can ST170 owners please post how much mileage they get from a full tank and any mods they have on their car (if any)

I would also like to know if a Bluefin makes much difference to MPG

2003 ST170
K&N air filter
280 miles per tank

 

K and N and cat back exhaust. 300-350 miles per tank

 

They are utterly terrible on fuel for a 2.0 N/A, most I ever got out of mine was 300, averaged 280ish!

 

I've had the ST170 from new, usually get about 300 mile p/tank, but I do a lot of very urban driving.
My wife gets about 75 miles more, if she drives it, but what's the point of driving at a steady 55...

 

I must be doing quite well then, and I was about to wine mightily about the poor fuel consumption. I did a run from Nottingham, to the Cotswold and then down to Weymouth and I got 312 from a not quite full tank to the light coming on. I have had the tank off and replaced on my 04 plate which is completely unmodded.

 

K&n and Catback im getting about 300ish to a tank think that equates to about 28/29MPG would get more if i took it on longer runs but i use it to work and back which is about 15-20mile round trip

 

My Old ST170 had

Mongoose Cat back System
K&N Typhoon Air filter 2
Auto Air deflector
CFM Short Shifter
CFM Vernier Cam Pulley
CFM Underdrive Pullies

Clutch Masters 12lb Aluminium Flywheel
Clutch Masters Uprated Cover Plate
Clutch Masters Stage 3 Kevlar Clutch Friction Plate
Dreamscience Remap

And would return
220miles to a tank

 

52 ST170 with 69k, K&N induction, 97 ron fuel, mostly short flat out journeys...

220miles to a tank.

Could stretch that to 260 on a long run with a very light foot!
