Lost in tuning ....
Hi !
After been away from the tuning world for 10 years and now I am struggling with tuning my car.
Short background, I have -68 Firebird with a LQ9 engine.
I have long tube headers, LS6 intake with CNC-ported LS6 DBW TB and Bosh "white" injectors (0 280 155 868) injectors. Until now I have used a Comp Cam XR265HR (212/218, 0.558/0.563, 115LSA).
The car has run nice with this for the last 10 years.
During the winter I decide to change the camshaft to a BTR LS1/LS2 N/A Stage 1 (223/230, 0.615/0.607, 115 LSA). After this, the car was not drivable.
I have made same changes so it is possible to drive it
I do not know how to proceed, is it safe to do the CALC.VET tuning under these conditions? Should I do something else before ?
kind regards Magnus
