Jon Jr really came through for me. Almost instant turn around time for a tune correction and the car has never run better. Very rare exceptional customer service! Thanks!
Jon Jr also wrote me a tune for my FBO set up. I went to Lund due to his reputation on tuning the KB Mono / PBH set up. Jon Jr's final tune was flawless in all performance levels. Each day if a data log was submitted by mid morning there was a email response with a tune tweak the same day. I later upgraded to the Lund Race Tune which raised the tq curve up everywhere from 3500rpm . After a couple of weeks on the race tune I went to 2 different Mustang race shops for Open House Dyno Days. Both shops data logged & assured me all vitals were safe. That was 2.5 years ago & it still runs awesome. I may differ from most here but I never liked the deccel popping that comes with enhanced tunes. Jon Jr. later wrote in Hang Timing which when coming down to idle holds the rpms up to around 1,300 rpm then drops to 850rpm after 2-3 seconds. The extra timing helped burn the fuel on deccel and the car now idles down smooth as ever.
That's an excellent write-up/comment @Jam421. Sounds like Lund Tuning is going to be in very good hands going forward. That was pretty clever of John Jr. to reduce the popping by adding timing to help burn off the fuel during deceleration.
