Recently picked up an 89 K1500 for a work truck, and am finding that these TBI units can be upgraded for not much $$. So, 700R4 is rebuilt and once I get new ball joints in, we'll see what kind of tuning can be done! Lots of things on the to-do list... exhaust is ate out pretty bad too - so will have to go with whole new better flowing exhaust too! :)
Been looking at the great info in various threads, THANKS!
