I have the predator running on my rig and it is set to the performance 100hp level. I dont have a RP guage and the lift pump is stock. Can anyone tell me what my numbers may look like. Not sure if I am draining the rail or anything. Thanks.

 

I ran the diablo on extreme when my truck was stock and I didnt drain the rail.

Nick.

 

you should be fine with just the predator,but if you stack it i would suggest getting a lift pump.

 

Running it on the Extreme RKL tune should put you at around 430hp. That's 80 morehp than the Performance tune so you are probably around 350hp..
I made 452hp/870tq with mine and I have stock injectors, LP, and CP3....

 

yeah, mine did fine with it on extreme, even at the track, i could still have alittle more fuel....

 

You definetly arent draining the rail! Believe me LOL.

 

Youre talking 350 at rear wheels I presume. Were those numbers with at stock tranny? I am afraid to run it up any higher, cause I cant afford a new tranny right now

 

I run mine on extreme all the time. In my opinion it won't hurt the tranny unless you bag on it all the time. If gun it off every light then it will probably rip at the clutches pretty bad, just driving and highway driving you will be fine. It all has to do with driving style. On extreme if I'm nice my milage is not all that much worse. I was caught one day on performance tune when a older mustang thought he was going to show me up, I had tough time keeping up, on extreme I would have left sitting lookin at my smoke trail.

 

Yes that number would be at the rear wheels...

The Performance tune would easily slip my stock clutch so I had to upgrade to an OFE. No more slippage even on the Extreme RKL tune...
You might easily hurt your trans on the Performance tune. Some guys get away with it and some break their trannies in a short time.

 

Yeah so far so good. I am not one for doing boosted launches are long burners.

 

i like my predator, but theres just too big of a power diff between 100hp and 160hp settings..... its like double it feels like...the 65hp n 100hp feel the same on my truck...but 160hp its like i've added a turbo n injectors...lol

 

10 4, same way when i had my 03

 

I agree there too. The Extreme RKL is a big increase from the Extreme setting too even though it is only 20hp difference. It smokes a whole lot more too...
I drive daily on the Extreme setting because the "Off the line" power is much better than the Performance setting....

 

i dont have a rail pressure or fuel pressure gauge but it feels like im draining the rail or lift pump is not keepning up. if i stomp on it in 2nd or 3rd on extreme is cut out and pops. rkl tunes are worse.
