I'm the UK distributor for Fuel Air Spark Technology (FAST) Electronic fuel injection. It is part of the TCI group of companys and it is quite simply one of the most advanced and easy to use after market fully mapable fuel and ignition control ECU you can buy.

 

Being able to plug in the laptop and tune the car from the comfort of the passenger seat as you are in the workshop or going down the road makes it very easy to get the road going tune of the car spot on, and when you go to the track you can use the built in data logger to keep a close eye on things. I would never go back to Carburetors now I've used fuel injection.

I also retro fit on to existing fuel injection car, giving you full control over your engine, this means no more chip changes
Fuel injection is not cheap, but for street driven cars you can not beat it, ask Nigel Parkin with the Jag, 20miles per gallon and 9.6@141 in full street trim including treads
This is Tony Cox's manifold which is destined for his 540ci Big Chevy, I used -10 fuel rail to cater for the Turbo setup planned for the future
This is Alan Williamson's 502ci Chevy engine which I built plus fitted and tuned the FAST system, first time out he ran 11.6 over the quarter and got 20miles to the gallon driving to Santa pod in his 3600lb truck
