im sure this thread has been bought up a million times but i cannot find the answer im looking for.
i know that to gain top results tuning is a must! BUT if i were to install HKS 272's into a VII that has already been flash tuned, walbro 255 lmh, upgraded fmic with pipes, exhaust (210kw at the wheels) can i escape without a tune after the cam install? or is it to risky???

 

better safe than sorry. tune her or you'll be taking chances at higher RPM's

 

you need a tune. period

 

yeah i thought id be pushing it if i were to do so, cheers!

 

i logged my car after installing gsc s1s before i got tuned and didnt experience a problem, except i didnt benefit from it till tuned.

 

Deff tune her

 

This.

 

deff but if you have to drive it to get tuned anything like that you can just drive it carefully and stay outta boost

 

Didn't we JUST answer this not long ago in another thread?

Yes, you'll want to get your tune checked, but there's no problem driving around in vacuum and not pushing the car hard.

 

Yes a tune is a must!

 

Eventually get one, yes. I've been running kelfords since July with no problem. Zero tune after 30k miles with current mods and zero issues. I'm very fortunate that it's still together.

I am in no way advising anyone to do what I did but you should be ok for a bit until you can get a tune.

It's a good thing I don't drive a subie

 

LOL I was thinking the same exact thing. It's fine to drive the car in vacuum. The cams shift the load values in the map which may cause knock or leaning.

Your idle may be a little screwy too, but if you have ecuflash you can simply add a few degrees of timing in the rpm/load areas at idle and that will smooth it out.

 

It's always better to have a tune done just so something doesn't break and let the car run properly
