What kind of car?

I can fit you a full sequential injected system and map it to suit your wants. Only if it is EFI though as i need to pick up TPS, 02 and injector pulse to make that happen.

If not i can fit conventional vapour draw system. But with those, yes you do lose some power.

I have laptops with keys for all my LPG computers, so i can adjust injection timing however i like. Usually i use it to get rid of flat spots or bring idle speeds up, but i can change mid range lpg injection pulse

The only thing i dont know, is if i can map in reference to boost. Im sure i can i just dont have a map in front of me.
