Ok, I am gonna try what I have before I go with anything else, so please nobody tell me to just get a Smarty, cause yes I already know its the best.......but free is free and nothing required of me except the time it takes doing all the testing of new tunes.........Knowing this, for those who have tested and tried all the custom Extreme "Hot" tunes offered free from Diablosport, which ones should I get??? I know they have a firmware update for mine that deletes speed limiter, so that is a no brainer, but what about the super extreme "hot" tunes???

 

Non stacker RKL puff tune.

 

Do you know exactly what that tune does???

 

Lots of timing, and quite a bit of pressure. I run it with my mp8 to get my rp up but the tune is pretty agressive. It does get a little warm with my stock turbo but now since my 64/65/13 the egt's dont get much over 1400.

 

I agree... Extreme RKL puff is what made my 617rwhp... well that plus 70hp from my VA box and a little spray of water.

 

Ok, well, you look similar to me (2003 HO). I took my truck to Phoenix Raceway about a month ago. The bad part is that it was HOT (108deg) even at 9pm! So nobody was making any good power/times. In fact, short of a 10sec Civic and a 13.99 Boss 302 Mustang, I was the third fastest! Fun!
My best time came on my second run, Extreme Puff tune. Puck at 100%. EGTs were outrageous, but I have now switched to a different gage and I think it may be a little lower..
The RKL puff and RKL tunes actually produced lower 1/4 times. Oddly enough, the 60ft and 1/8 times were faster, but I suspect my rail is draining even though my fuel pressure at the pump was good.
In summary, I think the RKL tunes are a little hard with a stock charger. You need to see what runs best.

FYI.. even with the heat (!!!) I ran a 14.11 at 99.9mph. Not bad for my mods and 2wd (ie very little boost at launch!). Couldn't be happier, especially when you consider the cars that were running slower! Some included (2) SRT Chargers, (2) SRT neons/calibers, a new IS3xx Lexus, modern Camaros.. etc..!

 

Ooops, I see that you have a diff turbo.. my bad. And sticks. May want to try the no timing RKL tune first?
