Gtt Running Rich/tune Advice

Hello my favorite people (most of you anyway),

Finally upgraded my GTT with a catback system (Venom Cat with a 3.5 Xforce System) and ever since then, I've noticed alot of backfiring which isn't severe, just very consistent - more so when letting my foot off the accelerator, and I don't even have to be flogging it to get it to backfire, probably 2/5 times. Fuel economy is also a bit so so, it's not bad but I think I could improve it a little.

I've read into this a bit and most of the advice of read into suggest I'm just running rich and the general way around it is to get her tuned, BUT, I've been advised I cannot tune a stock R34 ECU?

Is there anything I can do to alleviate running rich/fuel economy also, like changing out the O2 sensor or running some injector cleaner through her?

If tune is the only way, can I opt for a Nistune Chip over an AVCR because $1,000 + tune to combat the RR seems a bit overkill and my modding path doesn't include an aftermarket ECU (was actually planning for Nistune anyway - she's my daily so I dont want to rape her with mods)

What do you reckon boys and girls?

Cheerio!

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣

      Is the toolbox that damaged the boot seal the same item that fell on the car during the storm a while back?

      Who are you to deny yourself? I’ve said this many times to myself and apart from getting what I really want, I go quiet for a while whilst working out what I just did to my savings and how will I afford what it cost, then, next payday…
