I found someone here to do a tune on my 2004 Mini for all the mods I have on it now. I want to get it setup right to be more competitive in SMF.

My mods on it now are:
Rear swaybar
Adjustable swaybar ends
Strut tower plates
15% pulley
CAI
Miltek sport exhaust
Quaffie LSD
Wilwood big brake kit on front
Stainless steel brake lines
Upper Vibra-technic motor mount
Sprint booster
Megan high performance header
DMF flywheel conversion clutch
Koni performance sport shocks yellow
Hotchkis rear control arms uppers and lowers
H&R lowering springs
IE fix camber plates
ATI Harmonic dampener

My question is this I'm thinking about changing my injector from stock to the JCW injectors, replacing my 15% pulley with a 17% and then doing the tune, what have some of you done to get your Mini R53 setup for SMF?

 

In order of importance, I'd rank mods for SMF:

1. Driver
2. Driver
3. Driver
4. Wheels & tires
5. Suspension
6. LSD
7. Weight Loss
8. Power
9. Aero

A well driven Mini S on 275 Hoosiers at stock power level would be 100x better than a Mini with lots of power and any other tire.

 

Define competitive LOL What are your goals for the car? Are you still driving it on the street? Given your mod list, a better suspension would probably get you more time than more power. But as Burglar said, Hoosier A7 > other mods, and driver mod > all.

 

I agree with the others A7 first for SMF, but that said it takes quite a bit of spring to go with that much grip, and it's best to pair the suspension with the tires so you can fit as much as possible
