I will install headers soon. i just bought my predator a month ago and my car runs great with it! im hoping it does so after headers. Will i need to adjust any settings?

Yes, a custom tune would be nice once you get headers.

okay, is there a specific adjustment i could change. Right now without headers yet. ill hit 3rd at 80 and it loses traction! its great!

diablosport doesn't do/provide custom tuning...

for a custom tune for your gto, check out http://www.diablewtune.com

If i don't get a custom tune after headers, can i change the injector slope and PE and it be alright?

won't be 100%... because the predator only changes things in wide sweeping rpm ranges, unlike a custom tune where things can be adjusted more and with much better pinpoint accuracy...

plus, you will need a custom tune to disable the necessary trouble codes anyway... can't do that with the predator...

I won't have cats either. i thought the diablosport tune would disable the 02 and cat codes?

you can't do it yourself, but it may already be done in the diablo preset tunes...

i havent installed headers yet, but the last few days ive notice my car is being sluggish and my mpg shows 19.7 all the time. today i stomped on it while in 3rd and it did not down shift...

what software can tailor the DS tunes? i'd love to have a copy of it thats for sure

Post by **06MonteSS** » Sat May 07, 2011 9:58 pm

only the Diablosport CMR tuning software can open/edit the diablo predator/trinity tune files...

if you're interested in purchasing it, contact diablo's sales department... it's available for $2,500.00...

if you just need a custom tune for yourself/your vehicle, I do custom tuning and can hook you up... shoot me a PM if interested...

how custom can you get? is it as specific as say hptuners or efi live?

as an example could you set up some sort of lean cruise on the 05-06 cars? make TC kick in faster ... things like that ?

Post by **06MonteSS** » Mon May 09, 2011 1:05 pm

no.. lean cruise was only available on 2004 gto's, due to their pcm was different, from holden australia...

no lean cruise is available on 05, 06.... U.S. ecm/tcm combo, not a single pcm for both...

yes, diablo's software is like the other tuning software...

i dyno tuned my car today and had it installed in Predator,engine light for P0160(o2 sensors) still comes up after a few miles down the road even after tuner deleted code twice. Any info would be appreciated. Thanks.
