I have all the free mods done, thermal 3" cat-back, xtreme mbc and boost gauge...how much boost can i run safely on a regular basis?:rice:

15psi and dont go over it.
would help if you got a EGT gauge too.

Nice, Nice...that's what im running right now. Good guess for me! i have the walbro high pressure pump i could install too but i was thinking of getting the regulator b4 i throw that in...if i did throw it in could i boost a little higher?

yeah you could go higher than 15 on pump gas but learn what you are doing before you crank up the boost. what walboro did you get? with the 190 you wont need a regulator, 255 you will need one.

255

You will need a regulator for that 225. I have a 190 and I notice a huge difference. Alot more agressive on the throttle. Big time. More top end. And you can crank the boost to 17psi no prob. Make sure to get your gauges also. Good luck.
