PROBLEM with VE table and map sensor, and not a computer guy

[madmax85]

ok bear with me on this i am new to it ALL. i am running a fuel injection pro system on my 88 conquest. what version of megasquirt i have i dunno, i only have the ve table and not a spark table if that helps any. i am running the megatune2.20 right now but i have the 2.25 version downloaded and almost set up. my car is a race car and i want to be runnin 25+ psi of boost. the system came setup with a 3.0 bar map sensor. of course u can only choose the 255 or 115 kpa map sensor. i got my ve table tuned but when i made it up to 255+ kpa on the table it just shuts the fuel off, so i am stuck using 19psi of boost. how do you make the kpa setting on the ve table read higher, or what do you think is wrong, any help would be much appriciated. i check the board constantly so if you have any ?'s just ask

DIY auto tune has a 4 bar sensor you could use. Basically you need to change the map sensor then change the config settings to relate to the new map. I've never done it but I know it can be done.
