a good A/F

[diggitty]

hey everyone i just bought my first DSM on aug 9. its a 1990 GSX it just has intake, exhaust, manual boost control. also has turbo timer with the A/F hooked up and im running about 11.5 AF at wot. now this is a good ratio correct? this is my first turbo car so im still learning. im only boosting about 8 - 9 psi right now on 14b. thanks!

that sounds okay to me, I would recomend seeking out local reputable tuning talent to ensure that your car is keeping good mixture at all rpm's and temperature situations. It is cheaper in the long run and you can learn alot if you pay attention and listen. good luck to you. i dont tune my car cause i have the fortune to have a really sharp tunner avalible to me. I dont have a lot of cash and use a SAFC II. One day ill get the DSM link and what not. The boost you are running is safe just remember there are X number of hard runs in every set up so learn to drive the car and then save the hits till you need them .

You won't know what your A/F is unless you replace the stock O2 with a wideband sensor. The stock sensor is nearly a binary switch, telling the ECU either "too much" or "not enough".
