Out of the ones you have suggested, boost guage for one, but probably one with 20psi max. Having the 20psi just makes the scale a little bigger, and more use of the guage. The 30psi guage would be sort of like only using 2000rpm on a 8000rpm tach! The others, a oil pressure guage isn't a bad idea, but I would think that out of a stock turbo'd and limited upgrade engine, it will be of no real value. X2 for the temp guage, unless you are planning to take it to regular extended track days. For a newish tinkerer, the AFR guage would be the best other option. With it, you will be able to become familiar with what the engine fueling is actualy doing. You can see when the ECU is cutting fuel for overrun, and leaning out mixtures on lean cruse, and most importantly see the nice rich mix under load. If it is a decent (5V wideband) guage hooked up properly, you should be also able to see where the factory fueling is far too rich and that with an edit down the track, the fueling comes back more to suit max power rather than crude engine survival technique. After driving around for quite a number of years with a mixture metre on my car, I would feel blind without it. Damo

In the past, their was also a multiplication factor for engine size, regarding forced induction on engine transplants. I wonder if there is something simliar with the restrictions on ltr per ton for 'p' platers. It used to be something like x 1.4. Damo

03XR6T After a re-read, I can't find where "300rwkw on stock injectors with a tune only" was written,............ but I was saying, from what I have seen/read, the stock injectors are capable of around the 300rwkw mark, and basicly asked if anyone could clarify or deny. Based on your member number, you have been around for a little while, any ideas what the stock squirters flow in cc's? BTW, who is dynowog? Damo

One thing to rememer about injectors and their potential flow, is that they flow a certain amount fuel per minute. This basicly means that they are capable of flowing a certain amount of 'power'. What I have seen so far indicates that the stocko XRT injectors are capable of around 300 wheel kw (anyone?). So keeping this in mind, the injectors won't max out or cause a leanout until power is beyond 300kw, at any revs! A 3psi spike at 3500rpm won't push the injectors anywhere near their max duty cycle! So IMHO there would/should be no need to get another tune, unless the guy who did the tune has no idea what he is doing and has leaned off fuel beyond your everyday max boost limit. Do you have some sort of afr meter in the car? Damo
