Any tuners want to chime in? Is this something that happens quite often with this type of SC?

So educate me here. I’m considering the P-1X down the road and already decided against Lund for reasons unrelated to this thread. Question is: what’s wrong with the tune from procharger. Is it because it’s more conservative and /or most people already have a Lund? And what is ProCharger’s stand on this issue?
Looks like I'll be reaching out to you [MENTION=20966]diablomatt[/MENTION] for a tune if I go the Procharger route ;)it actually stems back to the factory calibration. for whatever reason some cal ids do iti and some don't. for example you can have a FSGK1 and it will surge its ass off. flash the car to a FSGM0 and apply the SAME tune and it will drive perfect.
also the intercooler has effect on it. the HO intercooler will surge way worse than the stage 2. the reason the PD blower dont do it stems back to the PD being a draw through vs the PC being a blow through.
i have 99% of all the surging figured out in all cal ids at this point. so yes its 100% tune related. there is NO hardware issues with procharger at all. its just the blow through TB is harder to tune and takes extra time. if any of you guys have diablo tools let me know and i can help.

I will say this...I had a very good conversation today with a very reputable vendor/tuner regarding this issue and I was basically told that this was a hit or miss issue, some get it some don't. I'm sorry but I'm not going to roll the dice and drop 7K on a system and then possibly get stuck with this problem. I believe there should be better transparency/input from procharger on this issue as it appears that these are not isolated incidents.

no, what you are talking about would not effect it. vac leaks can but simply teeing in would not.I'm assuming mine is tune related too. My previous tune was fine. I wouldn't think teeing off the BOV vac line to add a fuel pressure regulator would cause the BOV to not work properly and then have surging.
not a problem. would be happy to helpLooks like I'll be reaching out to you [MENTION=20966]diablomatt[/MENTION] for a tune if I go the Procharger route ;)
Go with your gut. Plenty of options out there when it comes to reliable and proven FI options. I haven’t seen this issue with the Vortech or any of the PD FI systems.I had a very good conversation today with a very reputable vendor/tuner regarding this issue and I was basically told that this was a hit or miss issue, some get it some don't.

UPDATE: spoke to Nardi over at Lund, sent him 3 logs containing 1-2 surge events each. He responded that he could see it on the logs, next day I get a revision, said to try it and if it does it to log it and send it back. Well as of 3 hours ago, I tried about 20-30 throttle stabs and nothing, couldn’t get it to happen. So as of now, I’m surge free. Props to Nardi over at Lund.
Not sure they would tell me, even if they would, not sure it would be true lolAny idea what was adjusted on the tune?
should have been figured out from logging tq source, etc, pedal %, and requested tq. little things will get you like not having the same values for tq to load and the inverse load to tq tablesits not imrcs. that's what i thought it was when i started trying to fix it. its the TQ tables.
and a few other little things. if he wants he can email me.
Thats awesome... I knew they would get you dialed in, and enjoying smooth free operation like the rest of us ProCharger owners...UPDATE: spoke to Nardi over at Lund, sent him 3 logs containing 1-2 surge events each.
