I drove another 340 Miles these past 3 days and used up 6.8gallons

Thats borderline 49/50MPG.

I only deleted the cold-air and used Diesel Kleen.

I will revert back to cold-air system and put a bigger 2.5~3in straight exausts (debating on flowmaster muffler).

Local Muffler shop is asking for $120 or so just to straight pipe it from header on back with 2.5in. I guess over $200 with a chaep flowmaster. arghh

Best,
bigC
