intake swap Hey guys! Ok I have a question. I have swapped out the intake on my motor from a ls2 intake to a pro flo xt intake. Will it affect the tune on the motor as far as idle and deliverability? Nothing much changed. Same injectors cam is 224/230 112lsa .609/.604 18-6800 rpm. Its a 5.3 by the way. I did a swap in a 74 c10 chevy truck

I would highly recommend getting your truck back onto a dyno for both safety reasons and to help utilize all the available power of the intake. You may be fine, but you will not know until you get it checked out. Do you currently have a wideband set up to monitor afr? Regardless, you dont want to be running into leaning conditions at any point throughout the rpm range. In general getting a tune when switching out parts like this is always a good thing, there is a lot of power to probably be made in the tune alone.

Nah I don't have a wide band. I didn't think switching out the intake would require a tune. You're probably right there might be some power made with it. I get it on the dyno once I get it goin.

Yea it should run but probably not the best. I just installed a bbk from an ls1 intake on a friends H/C 99 bird and it didn't really like idle or anything above 3000 rpm before a tune, its been very finicky. This is not all to say that it wont run, I would just be very careful with it in the higher rpm's. Its most likely seeing a whole lot more air than it thinks it is and isn't giving it the fuel that it needs.
