Anyways back to the 1.03 Tune file itself, So far I have been running the file 1.03 "Base Boost1.2.vft" tune for about a week. The good news is so far it has not set any fault codes.... The bad news is (at least for me) i found that 1.03 has less power than even my first tune file from last year from OV 1.01-g-c. Honestly, it seems sort of close to stock from the best I can tell. I will say in Matts defense I have not contacted him OV yet to check on if this is normal. Also, the temps are pretty hot here in NC, they have been in the upper 80s&90s so I can't say for sure yet, heck it may set up more for colder weather. I am running 93 oct fuel (the highest I can get in my area of North Carolina). Also, it seems like with this tune the trans shifting pattern and gas pedal seem dialed back pretty close to stock. I even did the reset engine and transmission learned data as I always do anytime I change a tune file. Yesterday and today to really compare I decided to switch back over to 1.01 G-C….. and it was honestly a big improvement over 1.03. I may just stick to 1.01g-c until I can get back in contact with Matt. Sorry, i don't have better news right now, but i hope this helps keep everyone up to date on how 1.03 is coming along so far at least for my car. Thanks!

I have bought and tested. The tune wins by a huge margin. Also, the OVT tune is only $200 more than the JB4, so its a no-brainer to get the tune.

I have a used JB4 for sale collecting dust if anyone wants it, but since the tune came out nobody wants them...

What people forget is the TCU tune also makes a huge difference and is probably my favorite mod. It changes the tranny from sluggish and reluctant to downshift, to snappy and rev-happy... how it should have been from the factory. I have both the TTI tune and the OVT tune and both are good with no issues so far. The OVT tune makes slightly more power up top, while the TTI tune is more smooth in the midrange. Both give lots of low end torque and remove the throttle delay, which a tuning box cannot do. Right now im running the OVT ECU tune, with the TTI TCU tune on top of it since with the TTI tune, you can flash the ECU and TCU separately. I still have my JB4 collecting dust, if anyone wants to buy it off me
