FINALLY went to the dyno and forgot my boost controller.

red line = last run blue line = first run

my very first f/i tune. i think i did alright but im pissed b/c i forgot the stupid boost controller. tq came out really flat for some reason. it had no boost creep and i have no idea what cams it has. before anyone says anything i know the dyno read 9psi but the map sensor read a steady 7psi.

in eCtune settings, uncheck the option \"Use PA sensor\" and use 1024 as the value, then check again, you will see that 2 psi dissipear; this happened to me. Good #'s for low boost =) My buddy with an 05 Saturn ION redline says my car pulls way harder than his... so I am eager to hit up a dyno!

no,no. that was the dyno thing reading it off of my manifold. i has nothing to do with the program.

nice tq curve. looks like that motor would be making power to 8.5K! customer didnt have a dump tube?

its my car. couldnt find any reasonably priced mendral bent piping in town so i jst said fuck it. it has stock everything so i jst left it at 8200-8300. i'd rather raise the boost then rev it higher.

For 80 to 100 plus 10 in hardware you cant get it cheaper than that. Some manual boost controllers cost almost that much.

Not much of a dyno shop if they don't have a spare MBC or five laying around they can loan you during the tune session.

Your torque is flat as a strap because there's no restriction to flow on your setup, yet. When the cam, IM, turbine, compressor - or most likely log manifold - starts being a restriction you'll see the torque fall off up top.

thanks for clearing that up Joseph.
