Need help on dyno graph comparison!!!!! Last year some of you may have seen my post about my car losing hp and torque. Well this spring I did a compression test (Checked Ok all cyl at 175) and installed new valve springs with an ls6 intake and TCI 3800 Stall. Dynoed at 341/382
I first dynoed my car with LS1 intake , LS6 springs , TCI 2800, And it dynoed at 342hp/389TQ All dyno runs are unlocked. That was last year then I lost HP.
According to NOGO at eastside , My car did pick up more CFM from the intake and should be showing about 10 more HP than it does on the dyno. Could my TQ converter be eating that power up, Car feels ok when driving it , just not sure where my power really went. He added 3% more fuel and timing is at 28*.
The bad dyno graph is the one the day after I went to the track , car only went 12.18 12.19 12.20 at 110mph. car just felt like it lost some umph.
