Lund nGuage tune

Hey all. Looking at the nGuage tuner from Lund. For those of you with experience with this tuner, what tune selection is preferred with the only bolt on upgrades being intake and axel back exhaust in the works? I think I got it narrowed down to the “performance tune” but just want to get yalls opinion. I have a bone stock 2017 GT. Thanks!

Hi ApacheDriver!

Ok, IMHO...……. run don't walk away from ANY mail order "tuner"!!!!!! and here's why....

It is important to verify the“Tuner” is ASE certified in your ECM & Trans programming & current. Plenty of persons advertise their programs tobe the best & offer custom tunes, but very few have credentials in theseareas. Some of these “geniuses” have caused damage to a few vehicles- just jumpover to & read comments from the MSE techs! Anexample of one of the more nationally "respected" tuners:

Roush Dyno Tune Posted August 26, 2012

"To make an extremely long story short. I need someone totell me who to talk to for help. I have posted several times and got a lot ofhelp. Got my engine build finished in May. Ran great. Took it to Roush Racingfor a tune. It is a 93, efi, 302 with several upgrades. Went to get it fromRoush and the water hose had blown and torn up my brand new hood I just hadpainted. It can be fixed. Drove the car home and it would not start the nextday. Finally found the adapter between the TPS and painless harness wasmissing. Fixed that. It would not idle consistently. Took it back to Roush.They said it was fixed. Went less than 1/2 mile and it was idling at 2500 rpm.Took it back. They were lost. I need help. I am totally disgusted. If you needto talk, PM me and I will give you all my personal contact info. Thanks for anyhelp. I am out of options."

Perhaps what is equally important is the parameters that canbe adjusted are set by the OEM vehicle software…so there is really no “magic”in what they are doing anyway. If youlook at the dyno charts from many of these supposed HP/TQ increases, they are typicallyaround 5%-7% at peak rpm ranges…….guess what, 5% is a standard deviation evenamongst mfg dynos and if you go to this link engineers at Ford racing have a article on just exactly how these “tuners”play games with the hp/tq ratings, how calibration can cause misleading dynoresults, & some of the “tricks” that are used to gain supposed powerincreases when in fact, mis-managing your engine….. and the most important itemis……these “expert tuners” (at least most) do not have or choose not to testtheir results (in comparison to the oem intakes) during actual vehicle motion(or simulation- such as a wind tunnel) as the oems do nor are these "mailorder tuners' regulated like any other auto repair shop in the if they"damage" your car...gee, sorry...sue me!

IMHO, if you live near any major city there are excellenttuning specialists with dynos who for the same price (if not less) will tuneyour vehicle taking into consideration your specific needs includingenvironmental conditions, for your specific vehicle. IMHO, the best bang for the buck!

Lund is a very reputable tuning company with top notch customer service. Your in good hands. With your list of mods pretty much any company will be about the same. Meaning maybe 20hp 20tq. I would not waist my money on a tune right now. Do more mods first. But if you are set on it e85 or flex fuel is your best power
