plenty of discussion on this. At that price, though, go for it. Be sure you check out the swap policy, and how much deposit you need to pay ontop of the tune cost. Will probably end up costing you around $400.

If you haven't modified your car much at all and don't want to for some time then the mailorder would be a good start. You will definitely notice a difference.

If you have modified a bit, or will be again in the near future, then save the money and get a proper dyno tune.

I got a mail order mafless tune from steve at oztrack. I have just basic mods (cat back, mcai, K&N, and gts maf pipe) and my car made 214kw at the wheels.

Car runs perfect, car uses less fuel, and goes much better. I highly recommend you buy one from oztrack, they are a reputable quality tuner.

I got one off ebay from apc_performance (one of the guys currently selling for $99, cost me $150) I have been really happy with it! For the money I paid there was a huge increase in power. My car is an auto and the gear ratios have been relaxed when in normal mode (revving lower at cruising speed using less fuel) and then with pwr mode it shifts a lot quicker and firmer getting quite taily shifting into second. I haven't had it dyno'd to test the rwkw but I can easily beat my mates VX Clubsport R8 from a standing or rolling start! The only other mod's I have done is fit an alloy OTR intake and cat back exhaust! When talking $$ vs KW it is hard to go past!

If you can live without your PCM for a week, they won't get you to pay a deposit, but if you want one of their's sent to you so you can do a straight swap you will have to pay a refundable deposit (about $300 or so) which gets refunded when you return it.

Hope this helps.

Yeah i got mine mail order from demon motorsport prob best thing you could ever do to yoursemi stock ls1. power increasewas mega noticable. mines manual and i noticed rolling down the road in 1st then giving it heavy accel itspun from first 2 2nd then to 3rd powers wikid now and the fuel lasts a lot longer whixh is a plus when you drive like a nanna. that was a full mafless tune and semi tuned to full 3" exhaust and 4 into 1s. and the otr and 25% underdrive pully

As far as I know, all my car has is the ebay mailorder mafless tune and a dodgey CAI I knocked up, and last dyno had 304rwhp. It does have a standard 2.5" exhaust though, don't know if that's standard to all LS1s or just the Monaro's

Hey guys,

These look very interesting, it seems that they are only selling them for 5.7 LS1.

Has anybody or does anybody know of anyone getting one of these for a gen4 6.0ltr??

Thanks.

If a reputable shop is selling their tunes through ebay (haven't seen any though), that's alright I guess. But all these low cost/high gain claims are BS.

[doobs]

As I said above, I have an oztrack mail order, he does sell some through ebay, I would say hes a reputable tuner. I base this on the fact I have a tune from him, my car has been on a dyno since, A/F ratios are fine, car runs fine, and makes good power. He has also supplied many mail order and dyno tunes for other people on a different forum.

I also had a look around before getting a mail order tune. The only problem with eBay tunes is you don't know exactly what you are getting and how they are long term. If you are running slightly lean, it will look good on the stats, but it will stuff your engine long term. Someone like Steve from OzTrack has got a reputation for tunes that are reliable long term, get good HP and don't damage engines. Some eBay ones may be excellent tunes, but you just don't have that some level of reassurance.

I ended up going with the OzTrack mail order and DuSpeed OTRCAI as it is a proven combination. The tune may be a couple hundred more, but an engine rebuild cost a heck of a lot more.

Yep you're spot on, I forgot Steve sells his tunes on ebay. His tunes, be it live, remote or mail order are fantastic. He has an awesome reputaion.

VT-VE Gen III/IV Dual Timing Table Mafless Tunes
Written by Steve
Sunday, 16 July 2006
This is our most popular choice of tune and usually results in a considerable gain in performance and overall fuel economy.
Dual timing table mafless tunes are now available for cars with the VT - VE Gen III./IV engines at a price of just $500. If its an Auto 6 spd this can also be tuned for better shifts for an extra $150
These are done using a new custom operating system made by EFILive. The usual Mafless tunes which are based on the VT-VY HSV GTS tunes calibration are only able to have the lower timing table as active. This gives less ability for the engine to be protected from regular low level knock. The use of an upper and lower timing table provides the added benefit of the car being able to learn its way upward and downward rapidly between the two spark timing tables adding engine protection and also better performance in varying conditions.
The Custom Operating system also has added tables;
Improved temperature correction of the air fuel ratios.
The ability to specify air fuel ratios at any rpm and manifold pressure.


The Base Tunes have been optimized for much more than just wide open throttle. They also contain some special calibrations that usually provide a considerable improvement in mid range power and fuel economy.

A recent customers LS1 Manual made 255rwkw (317 engine kw) on a dynolog dyno with one of these upgrades.
Pretty good for a LS1 with an over radiator intake, ported throttle body and metal cats. Still having the stock balancer and stock valve springs. The car has also been returning great fuel economy. Better than 30MPG on a trip.
A customer Peter did 12.98/108mph in his VY SS auto at WSID, its only modifications to support the tune was that it had an over radiator intake and a good exhaust system. It even had the standard diff gears. His son Steve beat his dads time with a 12.63/111mph in his VZ 4 speed auto LS1 stock cam, stock converter. It just has 3.9s, full exhaust and an over radiator intake.Recently both Peter and Steve have changed the cams in their cars and are both regularly in the 11.6s/116mph standard.
The fuel economy record on our basic mafless tunes is 816km to a tank. Paul from Gosford did this in his VY SS ute which is a M6. Its was around 8.2L/100km for the trip from Gosford to Canberra and back, to of all things the Canberra Summernats.
Many of our customers cars can get in the 8s/100km M6 or 9s/100km A4 on a trip and we also have some inner city customers who have reduced their fuel economy from 20L/100km to 13L/100km.

VE Commodore Gen IVs all gain heaps in their throttle response and part throttle torque meaning 6th gear can be used at a lower speed and they improved in economy. They also gain on the dyno by around 20kw at the wheels from just the tune. We have seen a few L98 270kw VE manuals make 286 kw at the wheels from minimal mods including a full exhaust upgrade and a quality over the radiator intake www.duspeed.com The same gains are apparent in L98, L76 and LS3.

We also have done numerous AFM equipped L76s and can advise on smart exhaust mods for them. They are able to be tuned to improve even further in economy because we tune them specifically in AFM mode in addition to the performance adjustments.
