Not Too Good After 5K

[TMW-R34]

Hey guys.

ive got ann r34 gtt and when i give it a bit of shit, its a little sluggy from about 5k until redline. feels like its not really firing properly and has a little trouble. It definanetly goes all the way but its not really smooth. I have replaced the coilpacks probably about 15 months ago, they are yellowjackets. Im not sure if theres a problem in the fuel system or something, any ideas and suggestion would be great.

thanks guys.

Is it stock ECU with more then 8psi of boost?

Yeah buddy, stock ecu, and theres about 11-12 psi.

thats probably why

the stock ecu has lots of protection on the ER34

turn the boost down 1/2psi and try again

keep repeating until you avoid the protection

then get a piggyback, standalone or remap solution

That makes sence. im currently a fourth year apprentice and will be qualified in the next couple of months so i was thinking of getting a bit of a tune up, possibly nistune or the like when the cash is a bit more available.

Would like to get to the 300-330rwkw so would of had to of upgraded the ecu at some stage.

Thanks a lot for the help mate, was worried for a little while there but seems to not be a problem with the car. so thats always a plus.

Thanks again mate.

yep just turn down the boost slowly bit by bit until you slip under the stock ecu limits

300 to 330rwkw is an expensive upgrade

its proably easier to sell your car and buy a car with that power level

it would certianly be cheaper. i reckon 15k at least in mods and labour

Never really thought about that lol. Its just i didnt want a car with that power already because it would have been thrashed to the shit.
