any body had any problems or know anything about stacking these two

 

This is a bad stack....the Comp has aggressive timing advance on all of it's levels and most programmers like the hypertech rely mostly on timing changes to get the additional power they provide. There may not be any power gain at all and quite possibly some surging and drivabiltiy issues as the result of too much timing.

Try posting in the performance section and you will get many more replies to this.

 

thats what i figured ,i had it on the truck for about two weaks with the map sencor un pluged and it gave my more power but about a weak ago my vp44 died with no warning

 

I am running this combo also with no problems at all and it has been this way for months but the map must be unplugged or it stumbles badly when coming off the peddle

 

hey john is that you

 

ya its me and ur just the guy i was looking for ,didnt u have a code for ur vp44

 

yes and it's still there and been there for 6 months or 15,000 or so miles. I have a feeling when your lp died it ran the vp dry and did some damage do a search on that

 

yea i ran it out of fuel two times in two days so yea it probley has to do with that but if u still have the hypertec i need to catch up with u sometime and take it off cuz im gona put injectors in it and my trans is geting weak

 

yea I still have it call me this week griggs has my #
