Did you have it Dyno tuned? I just got hptuners and a wideband so I was going to see about using an ss tune but I haven't got my laptop yet so I have no idea how to use hp tuners yet. I have everything to do the dod delete just waiting on some free time from work but if an ls3 cam isn't worth it I'll look into a different cam.SSpeedracer wrote: ↑Wed Mar 11, 2020 12:20 am LS3 cam swamp was a very minor improvement if any.

I use HPT. The transmission tune issue is only with some later model WN caprices.lastcall190 wrote: ↑Wed Mar 11, 2020 7:50 am What are you using to tune? HPT? EFI Live?
With HPT I have flashed transmission tunes independent of engine tunes and vice versa, with no issue. As for who I would recommend, I personally have Pat G along with many others. Chris Henry is another popular one. Also there may be someone local to you (perhaps another G8 owner near your location might have a recommendation). I would say I'm pleased with the tune.
EFI I only ever had on a manual vehicle so I can't properly comment.

No, not dyno tuned yet. The re-learning curve for me using HPTuners, its been 10+ years, was not worth it for me at this point. I spliced in SS settings and they work great. My time/money is better spent on the transmission and differential. I also have several other cars that are a higher priority.
Gotcha, was unaware of thatSSpeedracer wrote: ↑Thu Mar 12, 2020 2:38 amI use HPT. The transmission tune issue is only with some later model WN caprices.lastcall190 wrote: ↑Wed Mar 11, 2020 7:50 am What are you using to tune? HPT? EFI Live?

I did a tune on the stock cam first and was not happy with the improvement although it was decent especially when set up for 93 octane fuel which stock is not. I then did the LS3 cam and had noticeable improvement with no other big part changes made at all. If you look at the power being made by tuned stock LS3 powered camaros its pretty obvious that it is a decent cam and has great drive-ability and decent MPG. Our engine uses almost exact same heads intake and if you address exhaust I don't really see how the 0.2 Liter you give up on the L77 will matter. I chose it for all that plus the low cost and the fact that it will still run the DOD system although I have my tuned for off now. PS it will run on the stock L77 tune I tried it but big change after tuneNate68c10 wrote: ↑Wed Mar 11, 2020 1:35 pmDid you have it Dyno tuned?
