That's the same question that has been bothering me for a month now since I had my pulley done (stock software with 15% reduction pulley) that is why I have decided to order the 93+ Shark Injector.
Although Mini of Richmond, Canada said that it should be fine as long as I use 93+ octane and after checking the spark plugs for signs of running too lean (hot spots) which is not, I'd rather protect my investment and enjoy the extra HP & Torque that the upgraded ECU will provide. |
