Well i was told the tune cant fix it. Oh well - wish vmp told me this was going to happen. I would have just skipped the bap and got the return system. Oh well. Car still pulls like a freight train. Love the vmp blower so far.
Same here man. My tuner said not all of them do this. Think about this too, my tank has been dropped once, and now we think a line in there from the PPRV has come off so it's gotta be dropped again! And even if I went return or bought new pumps at the minimum, guess what I'd need a whole new tune. It sucks!

Don't feel too bad guys. When I first installed the blower on my 01 I ended up dropping the tank five times. I was pretty good at it by the end.

Tuning it will not always get rid of the hesitation. Every car is different. Generally deleting PPRV will always get rid of it, but people don't want to drop the tank, which is understandable, but again, the tune may not be enough. That said, as mentioned above, the PPRV can have hoses pop off and why I do not install them anymore. Once someone goes bigger blower we do a return system and no worry about dropping the tank more than once.

What's your thoughts on the Lethal Budget return kit?

No disrespect to them as I sell their products as well, but I won't sell the fuel systems as long as Fore is available. The design from Fore is better along with the quality of wiring. There are no hoses in the tanks, the rails clear all blowers unlike the divX parts. I have heard all the arguments about the short hose used and people for years not having issues with the divx and I say good for them. I have seen the same hose fail multiple times. I won't risk that with my customers.

I powershift the snot out of my car and I have a pprv delete and an upgraded fpdm and I still have this issue all of a sudden also and it's driving me crazy. Mine is so bad that all the gauges sweep like the car turns off and back on again, and I'm doing this on the track on full kill mode. I kind of do hope it is the fuel system and not an electrical issue because that could take forever to try and pin point it.

I'm glad I'm not the only one this is happening to because I thought I was nuts for a minute trying to figure this out and being the only person it's ever happened to.

Sweeping gauges mean electrical issues. It's losing power for some reason. I'd start checking grounds.

I thought so too. Not really sure where to even start because it's not on the launch where the initial shock of the movement of the car moves everything it's when I'm powershifting 2-3

OP -

We've performed 3 PPRV deletes in the past week at my shop. Banking that's what it is, I've gotta do one on my car this week. And @TRBO VNM great info as always sir!

Good luck. I just took a car in yesterday and the prior owner did a pprv delete on it and it has a hose popped off. Guy was wondering why the car fell on its face at 4500 rpm every time. Haven't decided yet what we are going to do. And what sucks is the previous owner knew there was an issue and bought a return fuel system just never installed it.
