Got a 1.5 remap,exauhst,007p and panel filter from rtech today and it was simply Awsome til about 10 minutes ago. I Was having a play with my mate in his integra type r.. on his private track..all of a sudden I floored it in 3rd gear and at 3.5k revs it started juddering and the engine management light came on. Tried to floor it in 2nd gear and the same hapened again. its like a multiple juddering and looses all power. Does anyone know what this could be?? I had two coilpacks replaced and i think rtech said all coilpacks were weak. could it be the other two coilpacks?? Any input is welcome and sorry for any mistakes made im on my phone.
