Mad Hybrid Review

[twildman]

Well,

I have had the hybrid on for a few days and have been playing with the tunes to get it where I want it. I am running Renegade Diesel 190/75's with the hybrid that has the cast wheel, stock fuel system, so this review is based upon my tow/daily tune only. I know I can drop the fuel pressure to next to nothing with my extreme tune, so I don't even bother at the moment lol.

First blush, not a lot of difference in the egt's vs the powermax. Boost comes on quick and will max the insight quickly. I need to hook up a mechanical gauge to see what it is getting to, just don't have the time.

After several tweaks of the tune, I have the egt's down quite a bit. Max I have seen is 1250ish at WOT in o/d at 100 plus (tested on a closed course naturally).

Cruising at 70 egt's are low 700s. 75 to 85 on flat ground I am at around 790 or 800. Boost is running around 8 psi.

I get a small puff of smoke if I nail it from a stop, and then nothing, truck pulls very hard in this tune, boost if comes on faster and harder than the powermax.

There are two distinct sounds from the intake side. A deeper howling sound and then when the boost gets to around 10 psi or so, it sounds like a leaky window on your house on a windy day. I thought I had a leak in the y-pipe or somewhere but couldn't narrow it down. Then I put my stock intake back on and viola, no more noise. The truck is really quite until you put your foot in it, then it will get a nice exhaust note, and just take off.

Overall, I am impressed with the turbo. It pulls hard, low egt's no smoke in my daily tune, all I need to do is hook up to a trailer and check it towing. I like it.

I have been working with Eli on his setup, 175/75 and the hybrid, and he seems to like it as well. I will let him chime in with his thoughts if he wants too.

I will be getting with Adrian to see about the new wheel and will update from there.

Sounds good Tony. I'm glad to hear that this thing can finally start being dialed in better with the 05 trucks (which I presume the truck you're running it on is).

I'm thinking Adrian will more than likely end up with a wheel similar to what Bryan is running when it is all said and done. Either way though, I think he'll be able to get a better wheel than the current one for the hybrid.

I really need to get a mechanical gauge hooked up so I can see what boost is actually doing.

That being said, where is the best place to get the reading from that is the most consistent?

I know you said don't bother, but what about your extreme tune for trucks running the hybrid and stock injectors? Got any tunes in the works for that? Still waiting to install my hybrid and try your DD/tow tube you sent me

I'm a fan of just T'ing into the MAP sensing line, but hey since you're a tuner, something you could try out and let us know how it goes is, (according to Bill @ PHP) you can replace your MAP sensor with an Edge EAS 0-100psig pressure sensor, modify the plug on the OEM wiring harness, and adjust the range of the sensor in the tuning; and you're done. Then you can read boost pressures all the way up to 100 psi in the factory location. I don't know if you have an Edge CTS or anything but this would allow you to pull boost readings through the OBDII port. I know a lot of guys like to have their boost gauges plugged into the intake elbow but I'm not a fan of that if you're pulling turbos on any sort of basis. Just my opinion of course.

I have written and extreme tune for Eli, and jwsland, I just haven't run it more than a day on my truck because I don't have the fuel system to support it, the fuel psi reading goes down almost as quick as the boost goes up

Tony, thanks for coming here and posting your results, I've been looking forward to hearing your input. I sent you an email because I want to try your tunes, my setup's in my sig. Pretty similar to Eli's I believe. Right now at 1800rpm I'm at 65mph, 5psi boost, and 1025*egt. That's on cruise flat ground.

Nate, I have an extra stock intake elbow and I'm thinking about taping it 1/8 npt and using a 0-5v transducer to read boost on my Dashboss. Right now it maxes at 23 then goes to zero. It doesn't seem like the truck is pulling any harder past that point though. What do you think?

[windrunner408]

That should work just fine Casey. Of course, I still think T-ing into the MAP sensing line is so much easier.

Awesome Tony. I'm running Adrianj's original style hybrid with 190/75's. I'll need to get a tune from ya to try out when i get the truck out in the spring.

Haha okay. I'll probably be hitting you up for that once I try out your other tune.
