Anyone tried these ITBs on their 3.0 16v ? https://danstengineering.co.uk/Porsc...t?search=944s2 . Looks like it also needs their EMS. Still, given how expensive it seems to be to gain HP, is this a decent bang for the buck? They are claiming 30hp gains. Downsides? Bad idea for a street-only car?

I am not going to comment on biggest bang for the buck. But if you go this way, look at DTAFast for T series ECU. The fuel map can be 30x30, MegaSquirt/MicroSquirt fuel map is 16x14, do not know fuel map for other supplier you mentioned. DTA also has ITB's
