Just picked up a 95 12v thats been built pretty good. I went and test drove it. It has a 4gsk but acts like it wants to only rev to 2200 if anyone can tell how to adjust them or give pucs would be amazing i have never dealt with 4gsk before.
Heres a list of the build on the truck
Aftermarket IC boots with constant load clamps
AEM dry flow with custom intake
370 Maine injectors
Tork Technology OFV
4gsk
181 Delivery valves
he351ve 6.7 turbo
ARP studs
South Bend Clutch 3250 plate load 1 3/8 input shaft
4" exhaust and 5" tip
Isspro gauges pyro/boost/fuel pressure and drive pressure gauge
Any tips at all i will be thankful for thanks fellas

 

I backed mine off and went 4 clicks it will free rev to 4 n I've seen like 3500 while driving

 

Sorry if this annoying but could you tell me how

 

Try to search it its pretty easy

 

Why do you assume it is a 4k gsk?

 

ill betcha the fella that sold it to him told him it was. might not even have an aftermarket spring
