Actually less laggy than the ht18.
Tuner says he is not a fan of mamba.
Says its hit and miss.

Its spins my 35 inch like there is no tomorrow
Overall im happy. Way more power and acceleration now.

Idle is at 820rpm now and when aircon kicks in it goes to 1200rpm. No doubt because of adjustment to main fuel screw.

I have disconnected the aircon up solenoid. Os this okay to do?

Adjust the vacuum diaphragm on the pump. Only needs a short screwdriver

John Thankyou

Im on a facebook page too. Some of the guys are bagging me out for choosing the mamba with the GTX blade. Personally I find it still much more responsive than the HT18. HT18 was crap as.

Honestly Im happy with the improvements

You still running a Mamba turbo?

The different compressor blades on a Mamba only make a small difference so it's no big deal choosing one over another. Ask the blokes that are bagging you out how many different compressor wheels they have tried on a Mamba 18g.

Thanks OB. This is what Im thinking too. Im personally very happy with the results. The tune is very clean. Much less smoke compared with the Ht18.
More response and more power.

The Ht18 in second and 3rd could barely hang on. Boost tapered off.

I just went for a drive again. Grinning ear to ear, Im one of them.

Definitely boost response is way better than HT18.
The power is amazing.
Im sure thats the 11mm pump doing its thing at the max too lol but still this is awesome.

I feel like Im on stock tyres and wheels again plus more!


I did have a giggle seeing the Mamba sitting next to the HT18. Big big size difference

So from reading some pages of the long Td05 sticky post

Overboard mentioned 6x6 blades spool slightly quicker but the GTX 11 blade better for top end power?
Less blades quicker spool, more blades slightly slower spool but better top end?
At the same time GTX blades are thin and light so really they all are similar?

Is this how these different blades work?

Hey mate good to see another happy camper. I'm a Mamba supporter too but I would say also that the difference is probably quite small. at the end of the day their R & D is obviously not the same as the big names so I'm guessing their differences are rather small. You can think about it til the cows come home but as long as you are happy I'd just sit back and enjoy.

By the way it's facebook after all, that pretty much sums up the comments on the GTX blade as it is. Nothing else really needs to be said.

So when is the new pump coming.

lol how much is a new 12mm pump?

Just looking back only over 12 months ago when I purchased the car
It was stock as.
Even no roof rack.

Now 35s, quikazz fan, Mamba
Im happy where its at Power, reliability and cooling.


Though I have no further Idle adjustment .
Im not fussed on slighlty higher idle.
Should I turn the overall fuel screw back?


Also one again guys on facebook said the tuner shouldnt of touched that main fuel screw ever
and if he did it stuff the timing up on the TD42ti?

Im confused

They have come a long way in their range, remembering they are just copying every other turbo out their and offering combinations of. But quality wise they haven't really changed much.

A standard mechanical pump produces X amount of internal pressure. This pressure is bled off to the pump's timing piston as the rpm advances. Increasing fuel to the injectors (when turned to maximum) the internal pressure reduces along with the timing. If it smokes up really bad or your fuel eco goes to hell in a few days, turn it back down until your happy.

Did he tune on the compensator or simply wound the fuel screw in?

Hmmmm.
The TCV style pump uses the PWM valve to control timer piston movement, the problem with adjusting the main fuel screw, is getting the TPS adjustment correct so the right signal is sent to control the timing as it should be.
It is a very rare thing to have to adjust the main screw however, unless the pump is tired or has been rebuilt and setup weird during that process.
It is a very unfortunate thing, but so many people simply concentrate of fuel alone, or even worse a AFR gauge, they forget about all the other things involved in actually tuning.

No smoke at all!

Very clean tune. Response is way better than HT18

Just idles around 820rpmto 900rpm but the idle adjustment is at its lowest.
Fuel consumption has been good too

Any detriment if idle is at this rpm? If not then im totally okay with it

God no.

He worked on the compensator. The fuel on boost and pre boost fuel setting.

He said he had to adjust the main fuel screw too while on the dyno.
