[outnumbered]

the spare TCG you can hear it venting more compared to the original,this i have noticed with normal driving. i would suspect that there is a bit off difference, i towed the van with the spare TCg i i had no issues.unless there is a average figure that it should be it is time consuming, i have checked my VNT on the VCT and it is in the specs that it should be at different test stages.
