Thanks for the info. Yes we do have 1 or 2, but we can always to go to UAE - Dubai (country next door) to tune and do all the modifications.If the OP is still in Oman I would first find out what is available to him as I mentioned above. Tuning and installing cams in a foreign country can be a nightmare if not thought out! If there are no tuners with Hemi experience in Oman, he will be forced to go with email tuning with someone here in the states. (I am only going by what is in the OP's profile)
IF, there are no experienced HEMI tuners in his area, it would be wise to contact someone like Sean at Hemifever tuning. He can recommend the best Cam, what other parts are needed and provide a basic tune from his numerous files for the specific cam he recommends. He will have a file for say the 270 Comp Cam that was installed in a 392 Hemi. The basic tune would almost be spot on if there were no other mods like longtubes. He has hundreds of files to start with.
For a Good Cam with MDS delete the OP needs:
Cam with limiter
Gaskets, recommend Cometic
All the parts can be obtained at MMX or another good Hemi shop.
2011-2020 6.4L HEMI MDS Lifter Delete Kit with 6.4 SRT Camshaft by MMX and Mopar for LX/LC/Jeepwww.modernmusclextreme.com
Unfortunately MMX do not ship to OMAN, I will need to ship it to my freight forwarder in NY, and it will be costly with the customs and VAT. I know Option 2 for non-MDS will be a pain especially in our area.
Sheeeesh... then I think I will go with Option 1: stay with MDS lifters, replace them and replace the oil pump with a Hellcat Oil Pump. Maybe disable the MDS from the ECU? can I do that? because I also hear that the MDS is also causing the lifters failure.
