Hello All..... Anderson Pms

Hello all I joined because I am looking for answers for the anderson pms. I have one installed and IU cant get this thing to run correctly. I detonated the thing last year and had to replace the pistons. any help would be great. Im in syracuse ny and have been a chrysler tech for 25 years so I have some knowledge but not that much in the thge way of pms..., car does well with part throttle pulls but can not run WOT. like it runs out of fuel. any ideas would be nice. thanks and nice meeting u guys
