Who has a VMP Gen3 TVS

I went from gen IIr to gen III in August. Had 2.4 on IIr and 2.9 on III. Twin 68 and JLT 124 for both. 662 whp on IIr and 680 whp on III although actually lost average power with III. Tuned for 91. Since swapped it out for KB 3.6 to go with full build and e85. Switch from IIr to III is not worth it if you are running pump gas IMHO.
Agree but hes not running pump gas. He'll get nice gains from the gen 3 on 100 octane and be able to pulley down.
Somehow missed that. Also missed he is running 5.8, I was on 5.4 at time.
For what it's worth, the calibrator/tuner skill set is everything. I can't stress that point enough. For every possible supercharger / throttle body / CAI combination, someone will have had a horrible experience with said combination and another someone will have zero issues and rave about the same combination.
As an example, I have a Whipple 4.0L supercharger with a (smaller) 3.75-inch pulley, mated to a Whipple Big Bore Monoblade TB (170mm?), with a JLT carbon fiber Super Big Intake CAI (155mm). I had been told (as well as read) repeatedly that this CAI was basically not tunable. Same with a monoblade TB versus a twin 65/67mm TB - and at the time a Whipple monoblade was not common. My tuner (Tasca Mod Shop) installed a custom MAF flange on the JLT CAI, and this combination runs no differently than the stock unit. I mean that sincerely - zero drivability issues. This combination produces 842RWHP / 750 lb.ft. on 93 pump gas. I forget that my 14 'vert has these modifications as it has been that good of an experience.
I'm not saying anything bad about any calibrator/tuner, but these forums are full of combinations that work great for some and the exact same combinations that have been nightmares for others. I wish you all good luck with your experiences.
I would rather not say.
Yeah he couldn't make my mono blade work, yet Jon Lund jr. Had no issue on my 2013 and Lund jr did an amazing job with my KB setup on my old 2013 GT500. But no shit I went to the KB168 and JLT148 and the car felt slower in every way. Went back to the twin 65mm T/B and JLT123MM intake and the car ran like a monster again. Needless to say I was pissed. But not much I can do.
I would rather not say.
It's all good. I only run MS100 fuel in my car, AZ pump gas in joke lol and we only have E54 so it sucks all around
I completely agree with you. Lund jr is the man. He made my 3.6KB on E85 run better than stock. I requested him, but it doesn't work that way there.
According to VMP's website the 2.6 pulley would be 20-21psi, 2.8 is 18-19psi, 3.0 is 15-16psi. I'm surprised Lund wouldn't work with you on the 2.8 for 93 octane, but I wouldn't feel comfortable running a 2.6 without adding some Torco to the mix.
Why hide it and put others through the same thing? This is a community where we should help each other out. How did you get rid of your tuner and get another one. I'm done with Alex and almost wrong off lund because of it.
Thanks man, I been wanting to do this one for awhile now.Or just enough
Good luck buddy, you’ll love the new power.

Not a bad idea. hey do we need to run a different belt for the Gen3? i have the one for the 2.4 upper but I feel like it's going to be to short.
Yes it was alex, the driveability was decent on his tunes, but the WOT power wen't down a lot and that was tuned on full MS100. I had to ordered a new tune to pass emissions and they sent me to a different calibrator (Dakota), I have always used Lund so I don't like talking bad about them and I'm sure that Alex is great at tuning the coyote engines just not sure about the GT500s. I just wish that if we wanted to work with Lund Jr than we could.
I had a similar experience with Lund last year. Started me off with one of their other tuners and he couldn't even get the base tune right. After several revisions the car was still going into limp mode immediately after start up.
Ticket was eventually transferred to Jon Jr. and he got it sorted out. I really hope I don't end up with one of the other guys when I submit a ticket for a new remote tune, but it seems that's the most likely scenario these days.
Jon Jr tuned my 2014 Paxton coyote car, my 2007 GT500 with the TVS, and now my home built TT 2018 coyote car. He is amazing.
Ive read that he is piggy backed on some of the tunes Alex is writing where customers are complaining so jon can take a second look. Hopefully that's true.
not to Hijack but This is what I was told as well. I was told he looked at my tune and didnt see anything wrong, but I have not had any contact with him like I had in the past tunes/revisions.
I was able to retain my gates 84inch racing belt by going from a Vmp 90mm idler to the vmp 75mm.
Also running a Vmp tensioner with the stock size 75mm pulley on it as well.
Yeah I have no idea if that's true. like I said I have always used lund, but I have tossing around the idea to start using palm beach dyno. Everyone seems to be very happy with them.
Definitely worth a shot. Nothing but good things coming out of PBD lately.
I wouldnt go PBD either, PM me if you want to know why.
Wondered why you took that combo off your car! Going to be nasty with the Gen 3 though.
