Tuning An Pfc For My R34 Gtt

[JustinP]

Well I have had the PFC in for a couple of weeks now and am about to decide on where to get it tuned (I'm in WA). I have narrowed down the tuner to either Top Racing (it's close to where I live and it's a small tuning place which I guess might mean I will get a more personalised service from?) or X-Speed (which is a big tuning place that might have better facilities, but might be be a more get you in and get you out experience?).

What do people think I should go for?

Also I am only aiming for around 200rwkw at the moment (I have turbo back exhaust, EBC which will be running 11psi etc...) - obvioulsy my injectors are getting to 100% duty cycle and I should not need much more at around that power level, but would it be wise to upgrade my fuel pump or get an adjustable fuel regulator before the tune for safety? Would the adjustable fuel regulator allow me to squeeze a tiny bit more performance out of this setup? I don't care about the cost of the items but would it cost much to get either of these installed by a mechanic, ie is it a major job?

Any help is GREATLY appreciated

I just road tuned a mates r33 gtst after he just got his new PFC last weekend and it goes really well.. i am estimating around 195rwkw or so on 13psi which spikes to 14psi when its really cold.

the mods are

Front mount

Full turbo back exhaust

K&N panel filter

Apexi POWER FC

and some duel stage boost controller

stock injectors

stock fuel pump

I dont think it would have less then 195rwkw it goes great - should put it on the dyno soon to check i suppose

ohhh forgot to mention it gets up to 90% injector duty with stock injectors and stock pump.

So I guess I shouldn't need to worry about getting an adjustable fuel reg... It's just that I have already been seeing the injectors at 100% duty cycle on the PFC hand controller. Maybe this is just because it has not been properly tuned yet to make the most of the fuel being squited into the engine?

exactly. when i was doing this one - the stock maps was taking the tune down to 10 af ratios which is very very rich map standard so they will take fuel out of it and it will bring the mixture right which will also make more power.

So yeah the stock pfc map is set really trich - you need to get it cleaned up.

how big are the 34 gtt injectors? if they are the same as the r33 then 200rkw should be fine.

Cool...

So those with knowledge of WA tuners - should I go with Top Racing in Carlisle, or X-Speed???

[Guilt-Toy]

No idea mate. i never even been to WA. ask in the WA section might be a start.

Between the 2 i'd go with X-Speed, get Ant there to tune it, speak to anyone in WA who's into performance tuning n Ant will be mentioned sumwhere. How much did either place quote u for the tune?

Expect round 195rwkw, dont be afraid to lean it out to extract more power & economy but watch the knocks. Noticed ur in Vic Pk, wonder if ive seen u round...

Are you serious???

Id be very affraid if you were tunning my engine!

Yep you probably have seen me around Vic Park - it's a silver 4 door R34
