New R34 Owner Need Some Help

[34sharker]

Okay so I just went and picked up my new 34gt-t the other day, absolutely love the car I must say but I took my friends 33 for a drive which is running around 290bhp opposed to my 340bhp and noticed his turbo comes on boost a lot harder than mine which is very gradual..I brought the car as is with the aftermarket parts and pro tunes it also came with the apexi avcr/power fc and I was wondering could I achieve a more punchy boost with adjusting any settings on the boost control or would the car have to be tuned again manually..any answers would be much appreciated and sorry for the noob question I'm only fresh in the import scene

You can start off by telling us what parts your running in your car, how much boost etc,, without that you cant really get a real answer

i dare say that a lot of the difference comes down to what turbo you are running.

Were both running the standard t3 turbo, at the moment I've got all the Alexi plug and play, apexi pod filter, big trust front mount, sard fuel pump, 3 1/2 inch jasma exhaust with high flow cat, running 0.9 bar roughly 13-14psi, makes around 330bhp, I'm not sure what he's running other than his turbo though..any thoughts on why his comes on so much harder?

you most likely aren't running the stock turbo if you are making that sort of power, even at 13 or 14psi, or your car isn't making that sort of power the dyno sheet is either from the car having more mods or it has been tweaked a bit by using different settings for the run, or is simply a high reading dyno. the turbo could possibly be a highflow unit, which would explain why his has more punch down low. also comes down to the state of the tune on your car, the compression of the engine and many other variables.

that said, the stock 33 turbo has a smaller exhaust housing than the neo turbo, so it should spool a little bit quicker.
