How much power am i making? Dyno..

Dyno request, or just take your word for it. I understand every car is different however my cables in the mail so I cant test my WHP yet, have a 2011 AT 335i jb4 stage 2, bms cp, 4" dp, and a 5" vrsf FMIC. Im thinking im around 350-370?

You're not going to get too far with just 93. The difference between 15 psi with good timing and 18.5 psi with good timing is pretty substantial. I went from thinking the car was ok to pretty quick with meth or meth and race gas.

350-370 sounds reasonable

Yes the car pulls harder on map 3 depending on what meth adder you put in. on map 3 you set the peak target by adjusting the meth adder and if your avg ign is 1.5 or below the car will target that boost.

In map 5 I do not know what Terry has the peak target at but it is higher than 16 psi. Map 5 is similar to map 3 as it will adjust your boost target based on your avg ign value. This is why the map will feel strong on some pulls and not as strong on others. If you were to log all of your runs you would see the avg ign value change. If you are running great fuel then you should be able to get full boost almost all the time.

Ok thank you bud ! But tell me with a high mix of e85 on map 5 can i hit high psi like your map 3 on meth. Also how much psi can the stock turbo take maximum ?
