Everything is just about done. Oil in the motor and its primed up.

I got a supercharged 383 bin file and several cyclone/typhoon turbo 4.3L files to look at but I got an idea of what to put in for a target from my experience trying to use a supercharge file isnt as help full as one thinks. they have a constant power increase at set points of the table. A Turbocharged tune has various points where it needs more addressing then others. Since a turbo vehicle gets loaded differently thruout the rpm range in various gears. best advice i can give you is for safe tune. anything over 100 g/cyl make your timing 8\* and anything over 115 kpa make your fuel around 115. this will net you a rich tune but it will be safe till you can start leaning the car out. now the when your boost starts ramping scale that 115 back down to 107 smoothly so you have a easier transition into boost. the 115 and 107 are referrring to the VE table. since a NA vehicle sees tops of 98% ve on its best day. as you start leaning the car out start playing with timing 1 degree at a time. not sure how intelligent your software is none of this might apply or it might. If you need any insigt feel free to ask good luck with your build!!! --- _[View the full topic](https://forums.speedlife.net/t/orr89roczs-1989-camaro-iroc-z-5-7l/188547)._
