jon316 Posted April 14, 2016 Author Report Share Posted April 14, 2016 Yea I've read haha, butit was free and it did help a bit as well as firm up the shifts so that was nice, but yea, no longer in use for sure. I am gonna talk to zippy about tuning the 5.3 though. Thanks again for the help Guys. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

jon316 Posted April 26, 2016 Author Report Share Posted April 26, 2016 Well problem is still there..replaced fuel pump and went through everything no codes nothing.

EXGM Posted April 26, 2016 Report Share Posted April 26, 2016 I thought you said was fine after you took the hypertech program out? You may want to do a compression check to rule out any possible engine problem. Quote Link to comment Share on other sites More sharing options...
jon316 Posted May 2, 2016 Author Report Share Posted May 2, 2016 Well it only does it while starting. Runs perfect otherwise. I changed fuel pump, I changed the wires once again to AC delco. Next is the spark plugs. I'm thinking could possible be a computer issue? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
jon316 Posted May 4, 2016 Author Report Share Posted May 4, 2016 Alright well the iridiums are in. Still have the issue. There's no codes, fuel pressure is good. There is spark. I'm guessing it has to be some sort of computer issue that sadly the hypertech may have fried. Even though I did indeed remove it and put everything back to stock. I ALWAYS run premium fuel. Oil pressure is great. Oil is also fresh. I don't understand. Sent from my SM-N910T using Tapatalk Quote Link to comment Share on other sites More sharing options...
