I did datalogs on the street and would email results and they would revise the tune and send a new one. The first tune they sent was head and shoulders better than the VMP. Funny thing is that Alex Flores did both my tunes, Lund must have a better base tune they build off of. I've never been on...
Sounds like the same way mine ran last year with the VMP tune. Full throttle and up to 1/4 throttle were good but half throttle range was embarrassing. Switched to Lund this spring and runs like a new car.

Get your car back and be done. When your in the UP let me know if you can swing by Iron Mountain area and we can take out my car, same Magnuson, 3.1 pulley, different CAI, Lund tuned with an MT-82 and see how they compare.

Well after a couple weeks of logs and revisions from Alex the car runs great and pulls strong. Part throttle where I had issues before are great. Alex ended up doing a great job for me, he answered my questions in detail.

Great, I just got a tune emailed from him today, but it will be about a week before I will be able to try it out. I actually just did a search for Lund Alex to see if he was any good.

I guess I'll be the minority and say my VMP tune and experience are not good. Part throttle surging issues, questions about set up that had to be repeated multiple times in emails. They said me going half throttle at 2k RPM in 2nd or 3rd gear is lugging the engine but they have me data log from...
My last mustang had a paxton on it, whenever the tune was loaded or battery was disconnected it would have a light bucking type surge when you first got to 70 mph for 2-3 seconds and would never do it again. Cars can be goofy sometimes until they learn what to do.

I got the Ford decal at Advanced Auto. Any issues with the email tune from Livernois? Mines a tuner kit and I still need a tune for it, talked to VMP and they said they could do it. May try the Livernois tune, just not sure who to go with.
