GMPP LS3 controller base tune Went to a local tuner to have my GMPP LS3 480hp tuned because I thought I had a bad tune from the factory. I get to the tuner and after some diagnosis work it was determined I had fuel pressure issue. Obviously we could not complete the tune and the tuner told me to bring it back after I fixed the fuel pressure issue. He also told me not to drive the car after I fixed the fuel pressure because the fuel mixture was very rich in an attempt to make up for the low fuel pressure. I fixed the fuel pressure but the tuner will not return my call. I only paid him for the work he did so not sure what is going on.
Anyway, I have a Dyno tune scheduled for Thursday with a local well known speed shop , should have went there in the first place. The question I have, should I spend the money for the dyno tune or purchase something like HP Tuners and reload the factory tune if I can find it. The car is a pure street car.
Thanks in advance for the response and my apologies for the long post.
