LTFT Need HELP

[Boomer4955]

I have a 2011 Corvette Grand Sport with a Haltech Super Bee CAI. I put the Diablo Tune in the car. My understanding that is the 93 octane tune. Well my LTFT at idle are 9.0 to 10.0 which is lean right? When I run down the highway at around 70mph, the LTFT are at 14.0 or better, is this normal or is this way too lean? Any input would be great. Also when I went to mod the tune that is in the car( 93 octane tune) I pushed the option (Diablo tune) but it then asks if I want to modifiy the stock tune, whats up with that? Please HELP. Trinity T1000 tuner has the lastest updates, Version v.1r09h

I did what you suggested, I read the link. So I did several scans and my LTFT at 1800rpm was a +10.20 give or take +1.0. Well I adjusted the injector slope by 5 (want to sneak up on it) now the LTFT at 1800rpm is around a +6.0 to +7.0, BUT my idle is pig rich like a -11.0 to -14.0. Also how come there is no adjustment for MAF in the GM tunes, I see the Fords you can. Any help would be appreciated, thanks.

those halltech cai's lean those cars out pretty good... I just did a custom tune for a guy today that has the halltech on his 2013 GS Vette, he was lean as well.. and with the custom tune, I adjust the MAF table instead of the injectors... changing the injector flow that much via the tool yes is going to make you richer everywhere since you're changing how much fuel they're spraying... cuz that's a big adjustment that's needed for those intakes...

I would suggest getting a custom tune done....
