sometime when i am in first or second and just take off for a second and let off it bogs out like almost stalls and kinda like slams the car forward.. anyone know or have simmular problems? mods are in sig besides the nitrous

 

I had a similar problem, I cleaned my TB and did the Sea-Foam brake booster trick and it went away.

 

My Auto did the same thing. took it in and it was marked as a lemon point. Warrenty covered it.

 

whats the sea-foam brake booster trick? i know what sea foam is but the rest haha

 

suck up sea foam in the hose that connects to your brake booster cleans out the vacuum lines
