Need help with basemap
 

Im about to buy a PM6 from Xenocron and he is going to burn me a basemap, but Im unsure of what I should tell him. It will be a DOHC ZC with a T3/T04e .50 trim .48 A/R @ .4 BAR. Im hoping to end up with 200whp, but will make that with slightly more boost, I guess I should leave my boost controller off until I get it tuned, and just tell him to burn the map for .4 BAR. But that turbo is going to make alot more power at .4 BAR than say a plain T3, so its going to need more fuel, but will he know how much more? Xenocron is burning the basemap...
