Wow, check out that torque figure from Shanes run. Is that from the SDS setup and the big intercooler?
Len, you might try to lower the base F.P. then jump it up using a Boost Dependent F.P.R. I was using a BDFPR with the stock injectors and all the other crap and made a best of 320hp give or take a few. The BDFPR is not the best solution but, it sure is easy on the wallet for the amount of HP you can run. You do have to be careful with the tunning though as weather seems to effect it some. As in the Dallas area it could be 75* one day and 25* the next. You don't go out and jump on it with that big of temp change till you have started at a lower boost pressure and worked your way up. Ofcourse you can just wait for the next day and not touch a thing 'cause the weather will be back to 75*.
