hello, im new to modding maps, ive got a VW golf 1.9 tdi 105 bhp, im looking to gain an extra 20bhp, i know i can get more but my gearbox is not the best so dont want to force much more through it.
So far ive only managed to edit my hotstart map using winols, what other maps would i need to edit to gain 20bhp safely ?

ill add my map as an attachment, any help would be really great. thanks for reading
