vmp did my tune. What is everybody's AFR when cruising. Mine was hanging out at 14.1 to 15.2 when cruising at 55 and 60. Had minor bucking/hesitation when cruising.

Wide open it was a blast and a definitely faster car.

Those AFRs are fine, if a bit on the lean side but nothing crazy at all. AFR will bounce naturally based on throttle conditions.

The bucking/hesitation is most likely a factor of the tune and depends on what other mods you have.

sounds like bad fuel. 91 or 93 octane? I am running a VMP tune & my car did not like 93 Shell gas. Would buck/hesitate/die. I quit getting fuel from that gas station in particular & no problems since. She loves Costco 93, lol. Cheap plus cash back.

Well shit. I just filled my tank up at the exxon I always get gas at. Never had a problem there before. Tuner is having me send him a log. I am sure he will figure it out.

Only FI company I’ve seen that can tune for shit is Kenne Bell. Everyone hates on them because they’re old school but I would take my better than stock drivability any day of the week in exchange for the 4 “extra” HP the other companies get you.

Well, VMP did an amazing job and I got everything sorted out on Friday. She runs and drives perfect. Lots of extra power up top and drivability is just like stock. I have no complaints. My tuner had me send pictures and we got the Vacuum lines ran correctly. The IMRC's work perfectly. I had issues because I needed to replace the actuators and had a few hoses in the wrong places. I couldn't be happier though with the tune and the help provided to me. I have since put about 100 miles on the car since I fixed the minor issues (on my end) and as I said, the tune from VMP is spot on and the car is making good power, at least if feels like it,

One of the 2018 vacuum actuators was bad?
Yea, they would get stuck either open or closed. One time the hoses where put in the wrong place. When they was corrected the actuators got stuck open. So I but new ones on and bam. Problem solved.

I have wondered if 15-17 actuators would fit om the back of the 18 manifold. If they did that would solve the voltage and plug format difference situation.

Now, see, I don't know why that wouldn't work. it would make life easier. I don't want to be the guy who tries it and screw something up.
