After posting that i had ordered the rp23 i received an email form a forum member as follows,
“I ordered one for my 5 spot. I thought loco tune was great price so wondered if tf did similar deal. Phoned tf who told me not to bother. Technician said all the talking of low/low is exaggerated on rp23 as difference in tune between middle and low was negligible. He said the difference was so slight that the importers are only bringing in medium tunes this year. I pointed out all turner threads went on about it but he said to ignore them. Talked me out of spending money with them so pretty honest of him. Didn’t want to start a stw argument about it by posting but thought I would let you know.”
Now i’m not trying too stir things , but if this is correct then theres no need to bother getting them re-tuned.
Loco , can you shed any more light on this?
