Hey all! Pleasure to be in this great group. I am attaching my first read and scan. Details on my Vette below.
94,000 miles & running great, I drive my Vette every time I can, love sports driving, Rally's, road courses.
I have been chasing an engine surge after I let off gas at speeds of 120 plus, typically not at slow speeds. It is like it is trying to get more fuel, I can give it more gas and it clears up but remains surging for an hour or two and clears up.
I took it to my Vette tech at my dealer and they found the low volume fuel pump pressure was at 87 psi (should be 57 +- 3 psi). They replaced a fuel pump module and the main ECU which they say sets the low volume fuel pump pressure. They said it fixed the high psi issue, it did get rid of the low volume fuel pump code. Still have the surge but going to fix it myself now.
I would also like to know how to properly edit my tune to disable the 4 cylinder drop if possible.
How to increase the top speed limit properly.
As I gain more tuning knowledge I will venture deeper into the tune. Hope I crafted this first request correctly and I really appreciate this HPTuners and this forums advice.
Thanks
Craig
