Brian, trust me, my Jeep has severe attitude problems and too much into it. And I swore I would never mess with my truck, but after a basic comp, intake and exhaust, it has now bitten hard. I just ordered a full B1 wastegated, Mach 4's, TST3 adj, Edge EZ, SB FE 13. 25 conv. Performance Diesel Warehouse estimates it should go 525 or so at rear wheels. Hope you have more self control than me!!
BTW, I am a noob member too. I am about 3 hrs from NN, 1:45 from Richmond, and about 45 minutes west of D. C.
