Nothing is safe with hybrid ebc's they over boost all the time.

why are you boosting a standard sr?
wouldn't it be wise to do exhaust & frontmount/intake first before boost increase.

i got a blitz boost controller...
just finished off the exhuast.

So now i have new aftermarket headers, 3" Turboback, Pod filter.

How much boost can i safely run? normal boost is 0.75 bar right?

After the mods, i tuned to 0.85bar, the car ran extremely well? it scooped smoothly to 0.85bar, but when i tune it back to normal 0.75 bar, it suggles to reach 0.75bar once past about 0.55-0.6bar....


Any help would be nice. :P

what you SHOULD do it put it on the dyno, pay your $50 and get them to turn the boost up as far as possible withoug damaging the engine.

thats the help youre gonna get :P
