I want to see if you guys think I will get anything out of a tune.
The reason I'm questioning doing it is because I still have stock inj / fuel pump.
Tune is going to be about $200 and they tune it on the street with a wideband.

 

Also I have intake, intercooler piping, full exhaust, and a boost controller

 

its always nice to work off a good tune. When you get a fuel pump or new mods etc.. just try to get the AFR back to how they tuned it. Then slowly increase timing to see how much you can get away without knock.

 

Only if you want better mpg, quicker spool and about 20 hp.

 

Thanks guys, some one just scared me the other day when they said I shouldn't waist my time getting tuned until I upgrade the inj & pump. I knew better but just wanted to make sure. Thanks

 

You don't really NEED to change the injectors on the stock turbo, but a pump before tuning would be good insurance.

 

Stock injectors are fine for a while. With the power I am currently running I only hit around 85% duty cycle. When running methanol the duty cycle is even less...

 

I agree.

 

Wow I would think the inj would be almost maxed out w/ 357whp running your mods.

 

I gained 80whp from a tune while still on a stock turbo and injectors.

 

Ok so the shop called and told me the injecters are maxed out????? They told me they had to turn the boost down to 19psi and now it's running good. WTF

 

Ask them to send you a datalog showing this.

 

Yeah good idea. It really doesn't make sense. I need my car back though so I have to pay them today. I'll ask to see the datalog whenever I go get it.

 

So I take that as a yes.

 

What are your other mods?
