VPGTS76 ill have to do something about it. The guy who is doing my loom said they change the signal output from 4 cyl to 8 cyl or something along those lines in the computer to give a accurate reading on the cluster, dont know if it’s true or works properly ?
That is one way to do it however that way seems to cause issue and not be accurate.
IMHO I believe that is why from factory they went down the 4 Cylinder cluster option.
I have calibrated Gary’s 454 LSx and other LSx and they all have been faultless.
