2G Help Tuning! First 3rd Gear Pull

jm1080 · 10-22-2009, 04:30 PM

Hey everyone I tried asking for help on dsmlink forums, but no help, unfortunately. By the way my mods list is up to date, haven't installed the 1050cc injectors or walbro pump though, still stock 450s and stock fuel pump, until I fix problems and learn to tune. Anyways what you guys think of this 3rd gear pull?

First time trying this, also for some reason my boost gauge reads 16psi but link reads 11-10psi.

Guess I have to learn this myself, cant seem to find help here or in link forums. Well if no one wants to look at the log can someone just tell me why my boost gauge reads 15-16psi and link reads 11-10psi? I remember reading on jeffgst site that airflow needs to be calibrated, so is that what I need to do? Here is site:

Also If someone can help me out on learning how to tune, step by step online, I will pay them something, just pm me. I'm getting tired of reading and not knowing exactly how to tune. Thanks.

Everything on my website is "Step by Step." If you have any questions while you are tuning just post them as you go.

As for your BoostEst problems, your intake temps are in 115F range which will decrease the BoostEst value by a little. But that is not enough to drop it below 10 PSI though. You most likely have a boost leak in the intake pipe inbetween the MAF and the turbo inlet. Check to see if that pipe is completely sealed, and your BoostEst readings will come back to the normal range.
