Actually, the later 300M's and the Special put out MORE than the "new" 3.5L's. But I'd still take the Kenne-Bell option if I could ...Archael said:There may be subtle differences but the output is the same as the 300M 3.5 which only has a program change from your R/T the engine will produce the same 250 if you reflash. It will produce more with the Kenne Bell OPTII
The "new" 3.5L's are. But the 2002-04 300M (if I've got it right) are 255 while the Special is at 258. I'm pretty sure the SXT's are 250 for all years.Archael said:hmm.. i thought i read somewhere they were at the 250 mark thanks for that D
thats not correct. the 99-01 300Ms were 253HP the 02-04 regular 300Ms were dropped to 250HP and all Specials from 02-04 are 255HPD76G12 said:The "new" 3.5L's are. But the 2002-04 300M (if I've got it right) are 255 while the Special is at 258. I'm pretty sure the SXT's are 250 for all years.
The TQ is all the same, thuogh, 250 ft.lb. across the board for all years of the HO - LH and LX ...
I stand corrected - the 258 is ft.lb. for the Special. I suspect (though can't confirm right now) that the 255 is also ft.lb. for the standard 300M ...SHAUN said:thats not correct. the 99-01 300Ms were 253HP the 02-04 regular 300Ms were dropped to 250HP and all Specials from 02-04 are 255HP
You've got an '00 R/T, right? If so, you have two choices (as far as I know). Get the Optimizer II or get a 2000-01 300M PCM from a junk yard and have it programmed to your car. If you opt for the junk yard route then be sure to match up the SKIS and/or factory alarm components. If your car doesn't have SKIS (Sentry Key - that's the thick gray key) then make sure the donor PCM doesn't have it. If you don't have the factory alarm I think (not sure on this one) you need a PCM w/out the alarm. Or you can install the needed components into your car from the donor. Once these functions are programmed into a PCM I don't think they can be removed. It takes a DRBIII unit to do the programming - that's an expensive ($3-4000) piece of equipment and usually means a dealer.JVH1982 said:Hmm, then besides an Optimizer, how does one reflash their PCM to get more HP (say 255 vs. my 244)?
If you have a 2002+ then you're pretty much stuck with Mopar. Your existing PCM can be flash upgraded but I don't think the main program can be changed. If you want that you'll need to buy a newer PCM that is programmed at the dealer and then talk the dealer Tech into using a 300M Special program instead of an R/T program. I'm not sure all 300M's have a high-speed PCM! In know the PHP (Performance Handling Package) cars and the Special do but I'm not sure about the "plain Jane" ones.02R/T said:Yea, Im currious about this 'reflashing' thing too. Is it something you could do by yourself? or is it a job for a Mopar Tech.?
On my PCM there was only one 16" size choice - 225/60/16. Maybe it depends on the program. No reason for the high-speed programs to know the other sizes ...Torontofirecaptain said:I did find that the PCM can only be reprogrammed for the available stock tire sizes though. My Eagle F1s are not able to be put in. 225/55/17 is the only 17" size, and the 18" Specials, as well as 3 16" sizes.
