?/ Don't know mate, I didn't tune it.

Anyway it's not tune related, nor can any tuning fix it.

After fitting new plugs and the intake, which was a mistake, should have only done one then tested, car vibrates on idle and up to around 2500 rpm.

I noticed it instantly and exhaust is louder.

Thought maybe a bad coil.

I've seen a few vids on resonator removal on other cars with massive negative effects.

Strange exhaust tones and loss of power.

Can't find any evidence of improvement.

One article which was quite in depth mentioned intake resonators as crucial to that specific engine design.

Anyway, the engine was way smoother before, so I'm trying hard to restore that.

Apart from that it goes pretty hard, high rpm in low gear manual mode is insane.

If it aint the resonator then I'll try new plugs again, maybe go back to stock 6 spec standard.

If that doesn't fix it I might try drinking way more alcohol.

 

Why did  you change to 7s anyway>

      GOT SUM's RB34

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.

      215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

      That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.
