I thought there was a rule that HPTs have a turbo gauge, as well as the lower stabiliser on the radius arm mounts.

Unfortunately listing as a 'Turbo' is not a good guide as many non-"Turbo" models (LPT) are still listed as Turbo in ads.

Also IMO there is absolutely no benefit in an LPT. It is exactly the same as an HPT, the pressure and power is just limited to a lower level. No benefit in lag, mid range etc. The HPT just goes to 11.
Except I think the reason for the LPT was mainly longevity, less wear and tear. Not calling it a turbo may also have insurance benefits.
