I am new here on this forum however some of you guys I know of other forums (small world huh)
I am from The Netherlands and drive a '91 454SS with the stock 4L80E controlled by the stock 16147060 ecm always looking for info on chipmodification.

Trough the years I swapped the tbi for an aftermarket mpfi from Edelbrock wich really woke up my 496 with Paxton supercharger.
