I thought about lowering the throttle threshold voltage but in my scanner it reading higher than the threshold already. My enrichment rates were higher in previous attempts but I put them back to...

`I'm trying to tune in a Jeep SRT8 with a Procharger and it's not getting into Power enrichment? Staying dead set at 14.7 and not coming off of it. What am I missing?

Nice catch. Thank you, that's gotta be it

Thanks for the idea. Nothing looked out of place but there were some rear o2 codes turned off. But two codes that I noticed p0421 and p0431. Do you think they would the catalyst to show not...

Hey Gang, tuning in a C6Z after a stage 3 cam. Car runs great but in a higher gear and under 1500 rpms the car bucks like crazy while off the throttle. The cam is big but not practical joke big and...

How much control do we have to change the system monitors? I have a customer that has a Durango that we Procharged and tuned. Truck runs fine, no codes, all systems are ready but the catalytic...

Looking for a stock Toyota Tundra tune file. HP doesn't have any

Thanks in advance

Anyone have a tune file for a supercharged Tundra? 2019

Thanks

no one has any suggestions? Do you need to turn off the rear o2s from effecting the closed loop?

I've got a few Dodges coming back recently failing emissions for system not ready. Not codes that I'm aware of, just system not ready failures. My first thought is they have weak batteries. Is...

What issue? Is it dying?

I didn't think so. Someone was trying to tell me otherwise so I thought I would check. What is needed to rewrite the vin? Can you change platforms with HP, from a Corvette to a Gto or a TBSS?

I have a 2005 GTO here that possibly has an ECU issue. Car is going into limp mode for a voltage correlation P2135. Replaced the throttle body, tb pig tail and pedal and no change. If I buy a used...

It's all good. It did seem to chop a bit better but I really think his factory mid muffler was holding it back. It had headers and borla Atak and was whisper quiet. Thanks again for your help.

Thanks Spray Ram Hell cam. I saw you changed a ton of stuff. I didn't want to mess with the fueling and stuff because the car was dialed in pretty well already. I went over some of your idle...

Hey guys just looking to see if anyone has any insight on this. Cammed 392 Jeep SRT, runs great, fuel trims look great, wot is on point. Runs excellent overall and doesn't bog, jerk or die, except...

What are you guys messing with to get these things to chop decent with a cam? I've been messing with the idle torque spark Proportional table and lowering the idle and this cam still doesn't chop...

I'll check the catch can. Was was going to vacuum test it anyway just in case but I'm not to confident that is the problem. Usually the fuel trims are off on cars with vacuum leaks. Maybe it's...

The idle isn't surging really. It's just getting pulled down by negative timing. The torque numbers look okay until that spike which you can't see in the scan. During a live scan it reads low and...

So we have a cammed 2021 Camaro SS. BTR 225 cam. Car ran great, had an excellent idle. Chopped awesome. Customer brought it back saying it wasn't running right. Looks like the timing is...

Too many pids is a thing? What's the downside?

When it backfired it sounds like the exhaust but once it did, I stopped trying and started taking apart the front end. The timing lines seem to...

Customer brought me a mess. They swapped the cam on a 17 Silverado 5.3. Truck wont' start. Just turns over. Check this scan out. 137997

They said they filled it with E85 and set the tune to...

Yikes, they are the only game in town right now. Might have to start with a new ecu. I'd have hp ship it back with insurance and then make the claim when you receive it back

How are you setting up those histograms?
