Actuator Getting Stuck?

[seduced]

Did you tell him what you wanted when you went in? Or did you just say 'max power please'? Sometimes you need to be specific with yourself in terms of what you want, high numbers are great, but drivability is more important IMO. If you have a preference on how it delivers boost, then you need to make that clear so the tuner knows what you want. If you simply asked for more peak power, then he did what you wanted.

To be honest though, 290 on stock BF injectors is nuts. Yes its do-able but you are on edge all the time.

I

'm nervous on my 251 @10psi with stock injectors. Its great fun, but

I

dont like it 90% of the time. my stock tune is actually more user friendly, just doesnt shove you in the back enough, so

I

run 8psi which is enough to get me into yet keep me out of trouble. Saves my driveline a little more too, it is the family car after-all... need to take care of it.

Take it back, ask for a safer tune, less power but boosting early and harder. Replace the actuator if you must, but it shouldnt be too much of an issue on lower PSI. Forget the race tune, go for these: stock, economy, power and valet. Pay him to re-tune, negotiate a price since he has already done most of the work and drive happy.

Best to talk with the guy now you've got some answers here, give him a chance to respond.

Some good calls there. I've spoken to my tuner and tried to explain all that and he suggested I do the fuel pump to gain a bit more of a safety margin. He reckons the fuel supply was inconsistent and could be due to lazy pump, that's gonna set me back another $400, I hope it makes a difference otherwise it's a waste, he's gonna play around with the actuator and re tune it. Will be interesting to see what results he gets this time. This visit is going to cost $700. I should have asked him to change the fuel filter as well since he thinks that the car is having fuel supply issues, I guess he should know if it needs changing or not.

I'm getting the car back today or tomorrow, I'll post up the results.

If it's not too late I would recommend getting a complete intake pump all set up ready to go with the factory type ribbed plastic hoses. That way if you go to a surge tank later you can put the nice quiet stock pump back in. I also found that rubber hoses leave little bits floating in the fuel from the hose clips. I know the filter will get these out but I just don't like it.
