acceleration problems

[chopp_chopp]

ok thiught it was gearbox but am not quite sure now if i hold it in second (vx ss auto) manualy and slowly accelerate there is no power for bout 900 rpms then it comes good if i boot it same deal once the power comes on will spin the tyres and take off. its not flaring like a slipping auto just no balls like really bad turbo lag any info would be great

Does the car jolt at all?

[chopp_chopp]

nah man not really just feels really slow then takes off. From a standing start its fine but once under load and u go to accelerate has a lag about it
