Power loss?

[KCODE]

1986 GN 46,500 miles: TA 66 Turbo, 42.5 injectors, TT Chip, Walbo Pump with hotwire kit, 3in exhaust, 160 thermostat, scanmaster, BOV, Bosch 37 fpr, adujustable manual boost pressure, boost gauge, spring cleaning, stock everything else.

?? I have an exhuast leak I on the turbo side. I believe it is the passenge side header. How much power am I loosing b/c of that leak. Scanmaster numbers g2g would an exhaust cause significant power loss? Just doesn't seem to have the power it should.

Honestly, fix it and find out. I had a leak on the drivers side header that got progressively worse over time and after getting it fixed it felt like a different car, especially not having to smell exhaust fumes in the car...which would probably slow me down eventually..

If your car felt better before the leak and now does not, the leak may be the problem depending upon its severity. Lots of stuff other than an exhaust leak can cause significant power loss but fixing the leak certainly won't hurt anything.
