sr20det redtop, slight throttle problem, car bucks

[turboex]

Ok car was fine no probs. SO installed a emanage, and z32 maf, car is still fine. Then i install greddy intake and redo the piping and now the car bucks and jerks at light throttle. I checked the tps. And im not hearing any boost leaks, but at 1000rpm (m new idle speed thanks to this problem) my vac is at 10-15 and not the normal 20. Will just a tiny vac leak cause this much of a problem?? thanks guys, its late im tired hook me up with some help. Tomorrow i may have it figured out but i figured I would ask just incase someone has had this happen to them also.

Minot ND.......damn that is in the middle of nowhere....


anyway...sounds like a boost leak to me...if you go WOT does you does slightly taper off as the RPMS increase

Yep soon as boost starts it almost goes away. Except when like at 1500rpm under load, then the car cant even gain speed, just sputters untill i down shift.
Oh see tonight in ND it was 50 out so it was cruze night, LOL. But none for me cause my stuffs messed up. then its suposed to snow, LOL.
