Stillen Supercharger reliabiity

Sh0velMan

FWIW, I have heard from more than one person and from Uprev themselves, that the injectors that come with the Stillen kit are undersized.

Upgrading to 660cc injectors and re-tuning supposedly lets the tuner get a lot more power out of the car.

A local guy here was told by Uprev (he tuned down in Austin @ Uprev) that his injectors were @ 100% duty cycle on the 'recommended' tune from Stillen. Which is baaaaad.

Thanks shovelman. I will look into this. Has anyone else here heard a recommendation for increased flow fuel injectors with the Stillen SC kit?
Are you recommending this as a way to get more power from the car, o as a way to stop the stalling problem, or as a preventive measure against future problems?
Thanks

The car went back to IPS over the weekend to sort out the stalling issue. The shield that covers the Air flow sensors had to be modified to fit the 2013, but when put in place the stalling was nearly completely gone. IPS also slightly modified the tune to increase fuel flow at idle. The car runs perfectly now - no stalling. I am very pleased.
Of note my last tank of fuel was 15.85 gallons topped off. I got 290 miles out of that tank The trip computer read 43mph average.
The trip computer also read 28mpg for that tank, but 290/15.85 = 18.3 mpg.
So don't trust your computer to tell you your mpg with the Stillen SC in place, it way overestimates.

It's basing its calculations on a smaller set of injectors. Any time you change the injectors you throw off the mpg reading. I get around 18 mpg combined driving and my display shows almost 30 mpg. I just switched the display to outside temperature. I'd love it if someone figured out how to reprogram the car to account for the larger injectors so I can have it work again.
