Seems I got it right this time, mileage improved, has good power, starts quick [though it always has]. A bonus is the engine is very smoooth. Note: All minor exhaust resonace - drone completely gone. It used to have a minor vibration - drone at about 1,350 to 1,600 rom's - it's completely gone now. Another bonus, maybe this is one of normal outcome expected in the re-set - the transmission is very smooth, especially in cruise control, shifts quick, E-Z up or down hill. It used to bog a little going uphill, waiitng too long to increase rpm's, now it immediately boosts rpm's by even just a few 100's.
CONCLUSION: If you have after market exhaust with DRONE, But, have NOT installed exhaust grounding straps and you have not done the ECU Re-Set then do yourself a favor. Do both!
You just might be very pleased with the result. BTW, if you install the EGS be sure to have at least 4 - exhaust to frame.

Would you mind explaining what an exhaust grounding strap is? Thanks
