sr20det new turbo

[dk11789]

so i just upgraded to a hybrid t25/t28..... we got everything installed and instead of it being at 8 lbs of boost like factory it now runs 12 lbs and i was just wondering if bumping it up the additional 4 lbs would make a difference on the af ratios just afraid i might blow it up because i have no supporting fuel mods

does anyone have any knowledge of bumping up the boost on a sr???? am i freaking out over something stupid or should i step back down on the boost ??? thanks in advance

ohhhh and keep in mind i am not running a wideband or anything so i dont know what the af was before i did the swap
