I had the Diablo tuning in, just installed a cam and had it LS1 edit tuned and would like to tweek this my self with HP tuners, someone said they thought that many diff. programs in the PCM was not good and my damage it, any truth to this or is each program simpley a editor of the numbers in the PCM?
thanks for helping

 

I contacted Keith at HPTuners and asked him if going from LS1edit to HPTuners was ok, and he said there was no problem. So I would conclude that since you went from Diablo to Edit, you shouldn't have a problem going from Edit to HPTuners.

 

Bits is bits, they don't care who writes 'em.

But, if you buy used clothes at the thrift store,
best to wash them first. No telling what's been
left behind.

I've seen some mighty strange stuff out of the
Predator, values that shouldn't even exist, when
reading back via HPTuners. If it were me I'd pull
out the current tune for reference, but be really
tempted to snarf up somebody's stock .bin and
rebuild my tune from there, just so I know what's
been touched and what hasn't.
