Wich one is better . I have efi live and a buddy has ppe and he is still faster. I have built trans and intake down pipe. 5 inch stacks and a ppe boost valve the efi is 250 over stock.

 

Depends on whos Tunes your using. PPE makes a tune that adds over 350hp

 

x2 on the tunes, you can look like you go fast with all the black smoke , there are some pretty poor tuners out there for efilive. i vote efilive from a reputable tuner hands down over the ppe. at least thats what i will be going with

 

could be other things than just tuning causing problems, but a log of the tune would help and see whats going on

 

I have a bad tune for efi turbo dosnt boost till 20mph.no more boost lanches.and I lost all smoke and motor is real loopy.and don't have the efi tuner someone stole it out of my pickup.so was thinking ppe now can I put ppe over the efi with out my stock tune

 

if you put the ppe on there on top of the efi live it will only cause more smoke and less power.

 

It would make a massive mess of your ECM.... overlaying a PPE tune over an EFI live tune is just bad news... I would look into getting a used EFI live flashscan... and hopefully you saved your Stock tune somewhere safe... like they tell you to do first thing
