2.4 jtd 136bhp 1999 EGR blank.
I made up a blanking plate to fit between the egr valve and the manifold and also made a plate to blank off the inlet manifold end of the pipe. Being an early 1999 136bhp model there are no electronics so no warning light problems.
I have had a tuning box fitted for a long while, which has been turned up slightly (may be 175bhp) and the engine has always been very smooth, loads of torque from very low revs and still surprises me with the power at the top end even after 6 years.
Blanking both ends of the egr pipe has certainly not had any downside. It runs with no lag or hesitation. Hope this helps.
