I am looking to boost off the .05 bar spring daily and have it up to 10psi at the track with a boost controller. I am planning on making around 300whp at 10psi.

I'm wondering how it works to adjust my boost from .05 bar off the spring to 10psi. Would I need a different chip with the 10 psi program?

Also I am looking into 3in exhaust with a cat and muffler or would a cat be a big power loss?

Thanks

 

As far as adjusting your boost setting, get your initial tune on the higher boost setting, then lower your boost. And with a scramble mode on your electronic boost controller you can have high boost with the touch of a button, or just turn down a manual controller.

Switching chips for different boost levels is retarded, and will also cost more considering that the tuner will have to do multiple tunes, costing you more.

just run a highflow cat.. wont matter. also when tuning you tune to a boost level, at 7psi it reads from xxx columns.. from 14psi it reads from xxx columns.. If your only boosting 8 or 9 or whatever (anything under that youve tuned) it will only read up to those columns.. Now if your using different fuels then you will need 2 maps. I suggest not doing your own tuning.

 

you could control boost via boost controller. at best by using electronic boost controller EBC. good ebc will allow several settings from spring to highest boost level. i guess generally you do'nt want to run double of what your spring is rated for.
