Speed density? I posted this in the conversions and hybrids section and didn't get too much response. I have a bone stock 4.8 and a pair of t70's. I haven't bought injectors yet but I am looking at 80#. I downloaded HPT 2Bar SD and am wondering if when I install my turbo setup can I run and drive around on this tune until I can take it to a dyno tuner? Does any one have a tune they could let me try out? I looked at the repositor on the HPT site and didn't fine anything close.
yeah you can. As long as you stay out of boost, obviously. I switched from a stock map/maf and stock fuel system to 2bar SD, E85 and 80lb injectors and just had my tuner upload a base tune so i could start it and check for leaks before i bring it to him. The most 'driving' it will see is around the block just to make sure the brakes are bled enough. dont expect it to run well though

As stated in another thread asking the same question and also answered in the post above.
You will be able to drive as long as you never see boost. Just drive sensibly and normally but make sure mixtures are within reason so it isnt dumping fuel in like ****.
But if it is a tune intended for your base engine and all sensors are calibrated correctly then it will be ok to take it easy to get it tuned.
