Actually I had tunned on Monday in Turbotrix. I made 314whp/311wtq on dynojet.
I have 05 MR with downpipe, test pipe and catback, GReddy Prof. B II boost control and HKS drop in filter, oh and a voltage stablizer. No fuel pump tho.
The car pull very hard, the top end is much better compare to stock, but I have a question for everyone, my boost spikes to 23psi, and since I have no fuel pump I was a little worried, am I suppose to turn the boost down a little?
My gain setting is 7% and boost is 55%.

thanx

That's not too high, but you should have installed a fuel pump before your tune just to be safe.

 

thanx, but will it be safe for now?

 

It should be. I ran 24-25psi on race gas with the stock pump, but I only did it at the track. 23psi isn't a big spike really. It means you are at 21psi most of the time, which isn't too much for the pump, however, it's always possible that it could fail.

 

I see, thanx for the quick reply, I decided this weekend I am going to buy a fuel pump and install it! thanx

 

If you do that, you HAVE to get retuned. That's why I said you should have done it first...

 

by installing a fuel pump I will have to get my car retuned?

 

yes because youll be changing the fuel pressure and the amount of fuel that is available due to the new pump being able to handle more of a load

 

Yes, thats why Warr was saying you should have done the fuel pump before the tune.

 

I see.... damn, should have done it at first place...!!!!
but do you think I am safe for now?

 

changing the fuel pressure, this def. make sense.... looks like I should move on to my next stage(cams) early now....

 

would suggest you lower the boost slightly to 20.5 -- 21 psi max

Then you will prob have no problems what so ever with your current set up

When its time to add more mods like cams or what ever then throw in the pump and get re-tuned

enjoy

 

Can't you dial out the spike with the EBC so it's just a flat 21 or so? What happens if you lower the gain but keep the DC the same?

 

thanx so much AL for your profession opinion.... I wil do that...

 

actually I tried both, lower the boost % and keep the same gain and did the opposite

and the spike never occur, it's always under 22psi now
