I have an 03 cobra,2 run with original factory tune, and ran 2 seprate dynos,
old was with stock tune, anderson powerstack, mag catback, temp 87 deg
new is with stock tune, JLT CAI, mrt catted h, stock and mag catback, temp 95 deg.
Anyhow noticed lost some torque, possibly from the hpipe and peak numbers were not as good with the new setup. Temp was higher on second run also.
