Hi,
on the dyno I work on a 2008 Shelby with Steeda 2,7" Pulley and cold air intake.
this is my first 2008 Shelby i have to tune.
the car runs on 10,5 PSI but I cant get some power. Car still have 472PS and 626Nm
here the log and the file.
i´m thankfully for any help
look at your o2 mv one band is not active at all wideband reading?
I think your car is lean
o2 sensor work now. wideband shows 11.4-11.6 afr, 24° spark and 10,5psi boost but still no power...
That's pretty low boost. Sounds like you may have a leak, or perhaps belt slippage.Quote:

Has anyone experience how much boost a stock Shelby has and what boost with pulley?
24 degrees of timing? are you sure you're not fighting a retard? Have you logged actual spark advance? and source?
you should target around 20 on pump, readjust your BLK table
post another log with your mv actually working.
Im unable to download your tune. What version are you using?
got the problem, crank trigger wheel was wrong installed in another workshop. now the car make 607PS and runs fine. :-)
