How do you plan to “borrow” a tune? :shrug:Ok so I thought I'd share my experiences from today.
So after taking the car back to the shop that did the installs and tune, I took it to another shop to get a second opinion.
The second shop did an inspection and didn't find anything wrong (he inspected connections, lines, replaced the cai and took off the manifold to to check for anomalies).
After leaving the IMRC's disconnected, we flashed back to the stock tune (even with some e85 in the tank which made me worried). We took it for a test drive (obviously didn't gun it at all) and to be honest the driveability was substantially better, which is especially surprising considered all the mods were still in place. Like the surging was very minimal, it responded better on the throttle, and didn't buck that much. Only thing I didn't get to check was how it performed WOT obviously, which is actually my biggest concern. We decided that I'm going to bring back my stock injectors and we'll clear out the tank and put only 93 in it. Then he's going to let me use his wife's Lund 93 tune to see how it performs.
Before I left, I switched back to my original flex fuel tune to see how it drove without the IMRC's and good god it was the worst thing I've ever experienced. It stalled at least 3 times on the way home, acceleration was abysmal, and there was this strange popping after every shift. I'm not sure if that's to be expected after disconnecting the IMRCs on the same tune, but if the car was a 4/10 with the IMRCs connected, it was a 1/10 after. Disconnecting the IMRCs seem to not have any affect on the stock tune. The mechanic also pointed out to me that it never threw any codes on the flex fuel tune, regardless of what he did, which raised his concerns (and mine lol).
After tomorrow's test drives, I can give further updates. Anyone have any thoughts about today? It seems like Lund might be my answer.
My bad. What I meant was, I’m pretty sure Lund locks their tunes to the vehicle. Eg. You can’t share them. :shrug:"Can I tune more than one vehicle with this programmer?
- You may only tune one vehicle at a time. You may return to stock and tune another vehicle up to 5 times."
That's what I got from SCT's website. Hopefully it works out
None what-so-ever! It actually runs better than the stock manifold ever did and I love the more linear throttle feel. No more light pulse or surge when the IMRCs are opening or closing. Lund Tuned and loving it.Matt, are you experiencing any issues at all with the IMRC's locked out? Any bucking or surging down low in the RPM range during normal driving?
What hassle? (honest question).Are these '18 manifolds worth the hassle really?!
The hassle of getting it working properly and dealing with the IMRC (as you can see from the various posts) and then paying to get it tuned.What hassle? (honest question).
They are cheap and easy to get ahold of (no hassle)
The install is very straight forward. I did it twice to add lockouts (no hassle)
LOCK IT OUT the first time and have a reputable tuner hook you up and itll run better than ever before (no hassle)
I cant recommend it highly enough. I love mine.
I went though a TON of hassle trying to get the IMRC's working. LOCK THEM OUT. No hassle there. Get a tune from a reputable tuner and you wont have a lick of hassle there either. The intake and a tune is worth every penny over stock hands down, without a doubt, would do it over again.The hassle of getting it working properly and dealing with the IMRC (as you can see from the various posts) and then paying to get it tuned.
In other words, is it REALLY that much better than the '15-'17 GT mani and are you gaining at the top to lose elsewhere?
