I have no experience with the powerpuck or the LML but I do know there are many options out there that would be better than the Diablo. Plus I think they plug into the obd2 port which would prevent you from running an insight.
They don't plug into obd2. Goes under the hood. There's a lot of guys who like them, are there a lot better options yes. But for the money you can't go wrong.
Also, will I need to buy the EGT kit for the CTS Insight to monitor the EGT.
Yes you need to run a temp probe in the exhaust manifold.
I don't personally know the way it plugs into the cts. I would think you could…someone else may know...
I would go for a custom tune..
Not the cheapest option but well worth it. I know many that had problems with the TS module, but not many opinions lately about the powerpuck since all the custom tuning is out now.
I'm planning on adding EFI eventually but for right now this will get me by. Also the CTS Insight is just a monitor. I'll agree with your statement of many people have trouble with the CTS evo. But I'm just looking for something to get a little more power out of my truck.
$400 on what? I have to have a monitor or gauges so that'll be spent either way. And I've found the puck for $280.
But before I do efi I want to have the exhaust done. Gauges/monitor done. And some other things done.
Sorry i just looked at the general price for power puck and seen they were around 4. But take it from me. I have owned 3 duramax's. First was 05 lly had the banks 6 gun with pda. Ran like a striped ape but also ran hot. second was 04 lly had bully dog with the top tune unlocked (forgot what it was called) but it limped the trans all the time. I have ridden in two trucks tuned with efi by two different tuners and there is worlds of difference. My third truck is stock because of finances. I would not waist my money on generic fake tunes ever again.
I know where you are coming from wanting more power for less money now, but in the end its not worth it. EFI with a smart person behind it has done so much to the duramax tuning world. I don't have efi on my truck like I said because I'm not in the best situation right now but I have experienced the difference first hand and personally it is worth staying stock for a while and spending money right the first time. You won't regret it.
Ok that makes sense and probably end up doing just that. Just gonna take care of all the little things before efi.
That is my thinking exactly. but you might also want to wait on installing exhaust on you truck with out a tune since it is so new. I am not 100% but i know the newer trucks with the dpf and stuff are picky when you start messing with them. So you might want to call some one and talk to them. You can always buy parts and stock pile until you have everything then do it all at once.
