For those trying to contact me, Im on my only annual holidays dodging the cold in Indonesia with another 2 weeks to go and its been horrible... approx 28c everyday, 24c overnight...
I have an indo esim, but telstra is really bad, and even though I can see some of your texts, replying is hit and miss.The messages here are ok, but best to email me at [email protected] Im back on the 20th

I've got a huge apology to make, actually FB should be doing it for me...... I've just discovered dozens of messages i never knew I had as i get no notification whatsoever from fb, and some of these e messages go back to 2020.... and this is the also part of the reason I started a new separate fb page called Injection Connection which is actually my business trading name as both of these have been registered names since I started back in 1993.
Kalmaker is part of my personal fb page and thats the problem so my new page has my contact details or just google those names and you will find my email or phone number
So sorry to those who gave up.
There are a few businesses with this name, not sure how this legal, as you have to be registered in Australia... anyway the correct link to Injection Connection is

I've been doing some pretty cool stuff lately, along with my other page , Injection Connection, as well as my new web page which I haven't really done much there yet, BUT it does have the old Kalmaker website there archived if anyone interested...
Anyway how's this beautiful FE Holden wagon.. it has a Ecotec 4L60e auto setup and Marco had been driving it on some online chip that was really bad...
So I set it all up, and got it running sweet, no dead spots and the thing that amazed him the most, was how I tuned the trans to be more firm and quicker shifting which altered the whole feel of the car from a slush bucket to how it should be in a car like this...
His mechanic didn't know this was possible, and had already replaced the trans and was about to replace this one too...
Kalmaker has total control of the trans, more so than the later LS1 4L60E with EFILIVE and HPTUNERS
Dont forget to check out the Injection Connection fb
