But honestly man when there's two tuners that deal with kalmaker in Perth. Seems like more but nope , the main one tunes out of multiple shops with his kalmaker gear. And the other ones an hour and a half away Nd I've seen them ziptie clamp w2a intercooler feed lines to heat exchangers.....
I personally know 5-6 people that can tune haltech for me road or rollers.
It's the entire reason I went the LS pcm. Kalmaker and tunerpro is an extremely capable system when you have a capable tuner.
Spend 10k mates rates machining , buying part out parts and fully assembling it yourself. You get a little itchy trusting tuners that have blown up 3 motors of your mates in 2 years including one that's got valvetrain rattle , has been re tuned 5 times and dropped 50whp since the 20k mates rates 355 that was built 5000kms before and money was spent to replace the previous 2x 304's that were blown on the dyno til he went aftermarket and a new tuner.
The computers only capable of doing what someone tells it to do. You don't tell it what to do properly and it doesn't matter how good it is it does it?
