Tune for 5psi? Is it really necessary to tune my car for only 5psi of boost for a rear mount turbo? I dont plan on running anymore than 5psi period unless I get a tune. I will have a wideband, fuel pressure and boost gauge.
What do you guys think?

As long as you have a a/f ratio and the right timing you will be fine. Maf should help on the a/f. Would I put a 5,000 blower on my car and not get a tune. NO

Tuning is more important than any other aspect of a build like this....it should have been considered as an additional cost up front, as it should with any build.
You cant even properly/safely run most Head/Cam setups without tuning, so it should be considered an absolute MUST for FI tuning.
I would also assume you have added larger injectors...running them without a tune will cause your driveability and mileage to be terrible as well....
Thanks

It would be a huge waste of the money spent on the turbo kit to not tune it properly.

Well yeah. I never said anything about that. I just didnt know if the factory pcm tune was cablable of pulling enough timing and upping the fuel enough to compensate for the extra 5psi. Apparently not. So I may try a mail order but havent decided.

Just like I said over in the "How much for tuning" post - it baffles me that people will spend thousands of dollars on a build and then shortcut or bitch about spending the money on a proper tune... and then a couple months later, you usually see those same people posting how they blew up yet another engine... Yes, you need a tune for 5#!

I love how people come on here and ask questions but already know everything. When someone that has been around and has a lot of expieriance tries to lend some advice they laugh it off. Have fun throwing all your junk away and starting over.

When did I ever claim to know everything? I didnt start this tread to debate on whether or not I can put together a kit for under a $1k. Yeah junk LOL there is nothing in my kit that isnt a popular name brand.
