    This not an option for you. V6 cars are maf based, not like the v8s. There is no VE table to go to positive pressure. Your better off embracing the maf and running with it.

    There is a ve table as a backup up in case of maf failure. It can only read to atmospheric, no boost ability.

    You will tune your maf curve normally. As it is a different maf you may be out more than normal. But you should be able to spot a trend apply it to the rest of the table to get close and fine tune from there.

    So if I need to add a bit of fuel . I should just use the enrichment for idle? Runs real good but under hard acceleration after the idle is unstable and will die. So I figure it's lean. Will have wide band on it next week.

    Your going to need a Wide Band for your turbo setup. Oh you can use your Fuel Trims to tune the idle and any part that is not in PE. But once in PE it is all wideband from there.

    Keep up the good work on learning. Happy holidays.

    With a v6 is it possible to fine tune ? What tables should I be paying close attention too? Is there a good method using the maf?

    Is there anything to pay attention to? I just got a wide band on my engine and when I initially fire it it runs great at afr 12 , then slowly it climbs to 18. I know its leaning out. Ive got a Northstar Maf on it ,which is totally different from a 3800. So I believe Thats where I have to concentrait. Whats the first thing I should do .thanks
