[Thread Backward] Re: Mileage/Power Improvement After BreaMsg # 4937 of 8004 on Powerstroke Diesel Conference (1)To: Dave, From: Daryl Time: Sunday 01-25-98, 01:53 pm I was getting around 18-19 in the summer,F-350 4WD 4.10. Mine doesn't seem to be doing quite as good since it turned winter.

I'm making -direct comparisons between vehicles, not saying -that it should get the same mileage as a moped! - -If you're so damned in love with your truck, go -outside and hump it, and stop wasting everyone's -time with reading your drivel - I'm here asking for -help, not erotica..... - -I've driven 5 other Powerstrokes, and the worst of -those got 18.4, with the others all over 19. And I -haven't seen much of any seasonal variance in -mileage on my IDI. Given a conservative median of -19, that leaves me down by 15%, which is rather -much for my tastes. Again, this is poored than my -IDI, which consistently runs upper 16s, with a high -of 17.3. I've heard that DI should yield about 20% -over IDI, so this definitely has my eyebrows raised. - -To the other person who's responded thus far: I -can't see snap idle stuff affecting highway mileage -and top end power. When did the EPA regs affecting -diesels last change? I know that something occured -on 1/1/95, but am not aware of anything more recent. - -Dave - - On Sunday 01-25-98, 02:29 am, Headhunter said: --I have 3375 miles on my 97 CC 4x2 DRW 4:10 A\T.... --Also have an ATS Performance Chip...yesterday I --hooked up to my Horse trailer, weighing in at close --to 5,000 lbs...
