I think as soon as you use your tuner to turn off MDS you'll void your warrenty.They can tell it's had a tuner on it,if you have a big enough warrenty claim,and they go digging.MDS hasn't been proven to hurt the lifters if that's your reason for disabling it. You can bypass the mds by manually shifting it to 8th if you have the 8 speed,supposedly on the 5/6 speed trucks,putting it in tow/haul mode also disables mds,but i can't confirm that
Use Tow/haul
No, purchased it straight as my original hemi died 3,500 miles out of warranty.
Hate to tell you anything,but they were lying to you about modding it and still having warrenty,especially if you tune it.The dealer will tell you what they think you want to hear,but Ma Mopar will over ride the dealer,and won't honour the dealers word.
Ma MOPAR is who I bought the engine from direct. Never dealt with a dealer or third party...
I've bought a couple engines and transmissions from Ma Mopar,nowhere did it say you could modify them and still have warrenty.To retain the warrenty you had to have an accredited shop install them was about all they ever said. Lets see this thing in writing that says you can tune it or modify it and still have warrenty
Doesn't the MDS solenoids have to be blocked off physically and then tuned out.
That's the proper way to do it,but if he bought a 5.7 for a manual transmission Challenger,it'll already have the block off plugs installed. The manual transmission 5.7 and 6.4 Challengers are mds delete right from Ma Mopar
this seems to be the crux of the argument. who really knows?? you'd think engineers, after all these years, would not put a function in an engine if they had any idea that it could cause premature failures.
