3.5L headers

Re: 3.5L headers

Yes it could I'd be curious what injectors it actually has to make sure we can get the tune straight

Well this weekend I'm doing a seafoam and changing my plugs/wires. I could see if there is some labels someplace on the engine, perhaps I could find out for you....

Re: 3.5L headers

The only reason I ask is there was a small injector change I believe either after or during 2008 (I'd have to check) but it may skew your fuel economy readings if they did the whole thing pan to intake with the newer injectors. Not a huge deal just something to ponder

Could this mess with a tune since the MAS on the intake could be skewed?

Doh! - I just a email they said they won't do the tune - looks like you locked in another one! - They are however still doing the headers. (which these headers, exhaust and CAI, she is just screaming now for a tune, )

Re: 3.5L headers

Progressive at the time (Hurricane Irene) since I had a 100k warranty decided that the engine should be replace brand-new. It was installed at the dealership, so I'm going to assume all the right pieces are in her, lol. Although when I did the Energy Suspension sway bar bushings, I found my sway bar is the size that is suppose to be in the G6 GXP, so it's not out of the realm of possibilities..... to my knowledge everything is new, they ordered new injectors and everything, the whole engine was taken apart for insurance reasons.... metal shaving all over the place.

Re: 3.5L headers

Cant beat a fresh engine man!!!!! My only concern with that (and this is pure conjecture) is if you did a top to bottom swap IE did the 2012 come with injectors and everything or did you swap those off your 08?

Re: 3.5L headers

Its because its easier, loses a bit of efficiency but its easier to install and setup that way. Tuning G6's in general isnt impossible its the 05/06 thats the problem but your stuff says 2008 so you should be ok

What's interesting for me is the 2008 engine that I have in my G6 was made in 2012, lol! .... might explain why I get 35.6 MPG on the highway on cruise.... just a FYI, my original engine got hydrolocked at 38k (91k now)

Re: 3.5L headers

Indeed, I went to the shop yesterday, it's about a 1:30 minute drive from my house. They've done tunes before on G6's and they have dyno tests to prove it with pictures. I've already locked in $350 to install the headers (I saw someone one here put them on their 3.5L and I will order the same kit) and they will get back to me by the end of the week for the quote for the turbo. I told them to give me about 3 weeks to get the headers ordered and they said that's perfectly fine.

What's interesting is they suggested putting my turbo in the rear, which seems kind of crazy but I guess it's possible....

Re: 3.5L headers

Tuners are not the same as software engineers, almost all speed shops have tuners I only know of like two that have actual software engineers in house So far that place looks like all imports? Some sweet GTR's on there though!!!

Re: 3.5L headers

You do realize that as of right now I am the only person to ever tune the 05 06 LX9 right? Aka there aren't any monkeys but thanks for running your mouth lol Lots of shops say that until they realize they have no software and you're back in the same position others have been in over and over again as 99.9% of shops dont have in house software engineers. For the record 800 to 1000 is ridiculous if they think they have software support lol

Heres the scenario (unless something huge changes that hasn't happened in 7-8 years)

1. You'll get an honest shop who will say they screwed up and cant do it (I've seen this a few times)
2. You'll get a dishonest shop that will say they can do it fake the dyno numbers and you'll have a stock tune (I've seen this a few times as well)
3. You'll get a semi-honest shop that will order a tune from me install it and charge the everliving crap out of you (I've seen this once).

So what shop is it I'm curious? Wisconsin isn't exactly a hotbed of GM tuning/engineering LOL

I was a programmer in my past life.... I should get into tunes.... LOL

But there is one place in CT that has offered to installed my custom headers and do a 93 tune on my G6. They come highly recommended from my car club buddies in Dutchess County (me and my friend started a car club about 6 months ago, we got 45 active members) - I've also offered them 1500 (they asked for 1600) to do a custom turbo to my G6 and they said that it's totally possible, they will have fabricate it, but I'm willing to see if they can do it. (they said they would get back to me once they do some research on material costs)

They have 3 in-house PCM/TCM Engineers in-house, all this company does is modify sports cars.

3.5L headers

I will be getting dyno tuned from a place near me and 1900 to 2500 is ridiculous and a monkey could tune my car for cheaper. This shop guarantees it could be done at 800 to 1000 if its built.

Re: 3.5L headers

Okay well I will keep you posted when I finish a few more mods then
I will post up some dyno numbers

Re: 3.5L headers

Cat backs don't matter no biggie

so if I get a cat back I don't need a retune, but if I were to go catless itd be good to get a retune?
