Attention: TDR Forum Junkies 
Has anyone upgraded an older TST PowermaxCR to the latest version (R49AP)?
I have a R47 I'm thinking about upgrading. According to the TST web page (FAQ) -
"... The R49AP also has Adjustable Timing Advance and Cool Down (turbo timer), plus Adjustable Rail Pressure and Rail Pressure Gauge can be added to PMCRs with Serial Number 5000 or greater. If you have an R49, it can be upgraded to an R49AP with Adjustable Program without Adjustable Rail Pressure for $110. 00, or the Adjustable Program with Adjustable Rail Pressure and Rail Pressure Gauge for $135. If you have an R47, the cost is $165. 00... "
The serial number on my PMCR is less than 5000 (1200s). The upgrade explanation from TST is rather confusing. Can I get the Adjustable Rail Pressure and Rail Pressure Gauge for my older PMCR?
