C-16 Dyno

If you find a good trim file, ET will only allow you to install once. They will not allow all six injectors to have the same trim file. Have you found away around that? I also looked in all the MBN flash files and never found any trim files, only 4 digit.

 

You can install all the same.Can you pm me?

 

Them are good numbers. Nothing to be ashamed about.

 

Thanks for sharing you dyno reports. What turbo are you running?

 

Most non wastegated turbos will give you lower rpm lag. The wastegated turbo is designed to make high boost at lower rpm but needs to dump off at higher rpm to prevent overspeed. I have found wastegated turbos better than non wastegated due to most guys on the road like to run there truck between 1200 and 1600 rpms. C15 engine makes peak hp at 1600 rpm. Why install a turbo that does not turn on till 1500 rpm.? In racing application, where high rpms ar needed, most run bettween 1600 and 2300, that is where a non wastegate turbo runs well.

 

You can get a Holset HT 60 non wastegated which is a major improvement at lower rpm over the stock wastegated turbo even,but then if your planning to go over 650-700hp,its no longer the turbo to have because your overspeeding it.
