What your tuner did was set the base timing correctly.
If you have a boost controler, i suggest you set the actuator arm to 10-11lbs, then use the boost controler to get a stable pressure. With just the actuator, your boost pressure will change depending on temperature and elevation - and timing and AFR (leaner = hotter, retarded timing = hotter, both making more boost). A boost controler is able to account for these and give constant boost.
If you are hitting 17-18lbs then it may be the spark plugs getting blown, so lower the plug gap a bit and get the new fuel pump.
Until you change your fuel pump though, do NOT boost the car, ever. You will run lean every time you do, and this kills an engine quickly.

This is going to sound stupid but I didn't know you could have both! I do have a boost controller sitting in my back seat lol and it didn't go all the way to 18 but it did hit right below 17 so I'll check my plugs. Will my engine be running lean even if the AFR gauge says I'm good?
