Change Cat Or Gut It (Fg)

[Bellato]

Yes I know dyno numbers aren't everything. Haven't got time to go to the strip at the moment.

Yea the wheel thing is right but I was running 18's and mate was running 20's

Gentech have had a good rep overall, maybe just talk to the tuner and express your concerns and see if he is capable of delivering what u want or if hes at a wall with your set up, something might be there that is impeding the final tune or he just might not know how to deliver what u want.

seriously if your obsessed with needing another 5 kw to make you happy then im sorry but that's fkn sad

the cats we have are either weld in for pretty much any car or we have a bolt in cat to suit FG to suit standard dump.

Tyres as well as wheel size can make a difference on the dyno.

I have expressed this to the OP, but the car was presented to be tuned with a combination done by the owner, I know it has gone back for other issues, but it is not the tuners job to sort out why it's not making the power when they did not do the combo assuming the tune has been done correctly. If the tuner had supplied a package to make XXX amount of power then it is their job to make sure it does it and if it doesn't then they need to find out why, but if a car is presented with a combo done elsewhere it is just their job to tune it, if it doesn't perform it's not really their issue, but they should be willing to chase it but this may come at added cost.

Yea jet kit is really good at what he does and he has been willing to keep trying things to fix my other issues. I think he hasn't had much experience with things such as the id1000's and that's where my other problems are arising

Yes I agree with mick but when the customer is trying to did out what's holding the power back and is willing to pay then you'd think there'd be some definitive suggestions. The cat is most likely the restriction as suggested by him but hasn't been confirmed

And freaky if it was 5 difference I wouldn't care but it was almost 30rwkw difference..

Either way not sure how this thread went this way, just wanted a second opinion on the cat and will most likely be ordering one off mick and fitting it and then having a retune trough gentech. At the end of the day the power thing is my problem and something I have to resolve/wear the cost of, fixing my other issues with the tune the tuner is resolving and has been doing at his cost which is good.

Were u finding that it has a bad time starting and coming to a very quick stop it stalls ?

Does it have a high idle rpm ?

[bossmang]

didnt you make 295kw?

[Bellato]

Well been through a few things. First was still stalling with 680rpm idle but found out the 100psi fuel pressure was the cause so fuel reg went in.

Then stopped stalling but wasn't happy with the high idle so had it dropped back to standard (550) and started stalling again. He then bumped it up to 570 and still stalling. Then changed something like the throttle response to 1:1 and still same issue

Then most recently he put more timing in at idle as well as more air? Or something along these lines. I'm not a tuner so hard to fully understand. Still stalling but have gone back to Griffith for 2 weeks so can't take it back

Use to stall when pulled up in drive now only stalls when you up in park or go front drive to reverse. And only happens when warm and sometimes not every time

Yea but had a retune and made 294 and mate made 321

wheel sizes make fark all difference in readings

I made 440 ish with 20s (my surge pump maxed)

a mate with very similar mods made 446 or 447 ish with stock g6e wheels.

same dyno

Those are tune issues not hardware issues.

Freaky I lost 35kw changing wheels.
