First let me say we are still in developmental stages and have alot of bugs to work out.
We do not have a working prototype on a vehicle currently, we do have issues with getting a ecu program, but we are working on that.
Power as stated before was at the crank on low boost, I should not have said wheel, that was my mistake. We are predicting about 340-385 at the wheels on the 4.2 with low boost. There are still issues with turbo sizing and piping structure that take some time to work out.
I am happy to see that we have some interest and this project is not in vain. If any of you have the resources to tune the 4.2 please let me know, we can work something out. We have a programmer that will work for the 5.3, that was easy, plenty of them out there. It is the I6 I am concerned with.
