it'll all be stock when it's done lol. will update tomorrow or saturday when i get some nice pic's going

 

Hmmm, where have I heard that before HAHAHA!

 

^ Last time he went back to stock he wound up buying a GTM SC kit... This time maybe he's going for a full blown TT ...

JK, Wei already sent me some teaser pics. His cars coming along nicely.

 

I would hold off on the shift kit and see what the TCM flash can do by itself. It seems to be much more versatile and can probably "removed" later on down the road. The shift kit actually modifies the valve body using changes to the passages which seem more invasive.

My car happens to be at GTM right now and I am considering the TCM flash, but we don't know how the car will behave combining BOTH flash and shift kit. Doing more research now.

 

I am sure that Sam could tune the TCM to work well with the shift kit. He certainly knows what he is doing. I think that the biggest benefit of the valve body upgrade is for tranny longevity. The kit is not that expensive and I don't think that the install is that expensive either. By the way, the TT 5AT member with the valve body upgrade is SharpbyCoop (his thread is here: https://www.myg37.com/forums/engine-...e-shop-ct.html). I don't know if he had any TCM programming done though.

Nick the tuner at Mac Autosport did tell me that the TCM "tuning" was the most challenging part of my tune. It took a while to get it dialed in and it takes some road driving to determine how it actually performs in everyday conditions.

Good luck with your upgrades and let us know which direction you go with the tranny.

 

I'm not FI yet, but I have the Transgo shift kit, and I think it was definately worth the money. Faster, firmer, and more commanding shifts. I easily chirp my tires in 2nd and 3rd gear. The kit was fairly inexpensive on Summit and install was about $700 from a reputable tranny shop. Make sure whoever installs it knows what the heck their doing and you will be a happy camper.

 

Nice! What other mods do you have (intake/exhaust/hfcs??) and how much more HP are you making now (or how much over stock?)

 

Coolraz, I have a 2008 Infiniti G35 Sport Sedan Plt Grap, Fujita Air intakes, Custom Exhaust w/ X pipe, Black Betty, Transgo shift kit, Motordyne ART Pipes, Blitz Rvit, Optima Red top, Tanabe Springs, Uprev..dynoed on a Dynojet at 272 whp w/o Art pipes and Uprev. Not sure where I'm at now.

 

Terry, can you explain to me again why DS mode is better with FI on our trannies than MM mode, and how does the acceleration between the two feel now that you are FI?

 

Thanks for the info! Nice mods! You probably increased with the uprev quite a bit, it usually unlocks a good amount of power after bolt-ons are put in. I think the transgo kit may not chirp on an all-stock car, but I can see why it would on yours. Anyway, seems like a wortwhile mod for sure....putting on my to do list...
Why the Rvit, I thought that was only for FI to monitor boost etc? What's the point of it for NA or did you just get it b/c you're going FI later?

Yeah I definitely want to know why DS is better when you go FI, I drive in M mode probably 90% of the time (I know the best gear for each the corners on the twisty road to work )

 

No problem,

The R-vit is definitely good to have if you are FI, which is coming for me real soon, but it is still good to have even when NA. The R-vit has the ability to monitor AFR's, water temp, Tranny temp (with the right harness), voltage, and many other things. It can also control when you want your fans to turn on. The R-vit cannot monitor boost, so a separate boost controller would be needed. I plan on Supercharging, so I wouldn't need to worry about a boost gauge and boost spikes issues.
