I'm attempting to learn how to tune with crome. its my first time tuning, and like i said, I am learning. I started off making a map for my d15b1 turbo with the stock p28 map. changed the engine size to 1490 for the 1.5, changed the injectors to 450 (dsm bluetops), and changed the redline to 8000 (like ill EVER rev that high) My question is how do you incorporate BOOST levels into the tune? im only pushing 5 pounds and dont plan on more for this motor. any helpful hints? Oh, i jsut downloaded it about an hour ago. ill figure out where to host the rom file real quick. but anyone that has tuned on crome know how? any help would rock, thanks!
