Does it need a Tune?

[bocou92]

So I'm getting ready to buy an intercooler for my 02 GTP with ported LIM, and ported S/C. Would i need a tune for these?

Also, I'm planning to reduce my S/C pulley to a 3.2", but don't know what size of fuel injectors and what kind of fuel pump to get? Any advice?

if your on gas, 42 injectors will work. and you will need a tune, cause the injectors need to be tuned in.

You can run stock injectors on a 3.2 pulley. You don't really need a tune.

with those injectors would i need a better fuel pump to increase the pressure?

also, do you have any advice on the intercooler issue?

I wouldn't worry about the fuel pump, but a fuel pump rewire is a very good idea. you don't need a tune for an intercooler, but it kind of defeats the purpose of modding. just adding an intercooler and putting a smaller pulley on the car will make more power for sure, but nothing will change the mannerisms of the car more than a tune. your fuel pressure is going to be the same regardless of what fuel pump you run.

im on the stock fuel pump, no rewire either, with 42's and running a 2.8 pulley now. the wide band says all is cool. re wire might be a good idea tho just for sh its a giggles, even for me one day.
