Good tuners in Essex?

Gord Dave Read has used them Jim, ask Dave and im sure he will tell you not to even reply to any emails
Okey dokey, doesn't sound good.
I'm half tempted to have a crack at tuning myself. I know I'll prolly get dissuaded by most people, but as I've pretty much installed everything else myself I think it'd be quite cool :/

The last couple of times I spoke to TDI on the phone, they (Mark I think) gave very useful advice and promised to send out some small parts to me, free of charge, which I thought was great.
The advice turned out to be wrong, and the parts never arrived.
The fact that you like to get stuck in and do things yourself is great Jim, but do you really want to risk getting the tuning wrong? I have always been told to get a tuner with lots of experience, and you have none! I'm sure you know the risks of a bad tune, if not, ask someone with a Lexus mapped by TDI! :lol:

I'd tend to agree, but I'm always one for questioning the 'why' and here's what I'm thinking....
I think a lot of the "get it tuned properly" comes from the turbo'd crowd. I can understand why in this case because most of the time a turbo is capable of generating a lot more power than the car can handle. Also there's a very real danger of boost spikes that can instantly kill an engine.
Compare this to a supercharger where your PSI is is determined entirely by your max engine RPM and the only way your boost level will go is downwards if you develop an issue like a slipping belt..etc. This is even more evident in an auto car, when you can't even over-rev by accidentally slipping into the wrong gear.
Then there's the actual tuning. All my Emanage blue allows me to do is add x amount of fuel for any given RPM/PSI across a 16x16 field of boxes. Once again I can see why the turbo crowd would want it done properly, because the boost from a turbo is something that almost needs to be pre-empted with fuel added in preparation for when the boost kicks in. However, on a supercharger you can pretty much say that for any given RPM, the max boost the car will be making is xxPSI. It's very linear.
So then it comes down to optimal settings. Obviously unless you've worked on countless numbers of the same cars with roughly the same mods, there's no way to know what the best settings are, and even then every car is different. You just have to test settings and keep dynoing until you get the best figures. Obviously at the same time you need to ensure safe AFR's, but from what I've read as long as you're on your way down to the 11.5AFR range when you start producing decent boost, its a good starting point.
Then from there what you need to do is keep an eye on knock. However as my car is on a pigyback, the stock ECU does a pretty **** good job of pulling timing in order to avoid a dead engine. Best thing though is obviously to find that sweet spot where there's no/minimal knock, the timing isn't being pulled and you're still making decent power without adding too much fuel.
...and thats about where I'm at in my head. YES it makes sense to hire someone that knows what they are doing, but the complexities of tuning a supercharger at least, don't seem as out of reach for a n00b like me as the price of getting it done by a pro would lead you to expect.
With my setup at the moment I've already added a _rough_ 5-15% fuel across the map which combined with my meth injection is registering no pulling of timing and has the engine running at 'safe' AFRs of 10.5-11.5. But obviously this it's not making anywhere near its best power, which is why I definitely at the very least need to hire a dyno.

Gord I thought the optimum mixture of air and common gasoline is around 14.6 parts of air to every one part of fuel for an air/fuel ratio ?
Yeah that's the optimal AFR if you're not running boost. Here's some rough guidelines I've obtained from other boosted IS300 owners:
-10 14.7
-8 14.3
-6 13.9
-4 13.5
-2 13.1
0 12.7
2 lbs 12.3
4 lbs 11.9
6 lbs 11.5
8 lbs 11.5
10 lbs 11.2
12 lbs 11.2

Optimum for the most powerful reaction when the fuel ignites yes but that's not always safe. Don't forget you can use the cooling properties of fuel to bring in-cylinder temperature down and to make everything safer. On forced induction engines 14.7AFR can get quite dangerous.

RichyUK i can arrange to use the Dyno at Dynotech in Erith and map it for you, i map there quite a bit
Oooh sounds promising mate. How much would I be looking at $$$ wise?
I also just got an email back from Fusion Motorsports with a surprisingly reasonable price. SO it looks like I may have a few decent options open to me

yeah ed would be able to sort you out ok. i'd say you'd be looking at about 250 to do it
