Evo is super laggy
Just got my new motor built already put 1k miles on it and drives awesome with no issues during the break in period
noticed that at stop lights or taking off the car has no go and takes forever for it move. Running a GTX3582R turbo before the build and never had any issues
compression test are fine 140 across all cylinders except cylinder one that reads 128 but was stripped from the previous owner and had to fix it. Pistons are 9:1 compression
i did have the head ported fully, exhaust, intake, and valves
my tune is on July 7th, im ruling out that the head has to be the reason why. Does a ported head really make that much of a difference if its not tuned?

that is a big turbo.
before the build would u be able to remember your compression figures?
have u done a boost leak test? did you change cams while building?
and yes, a ported head would need a retune.
a tune might be able to solve that.
but a built engine should definitely be less laggy if you have gone with higher compression pistons

Before it ran fine, but the head was never ported and thats what im thinking. It might need more fuel
but I went with a 9:1 compression instead with 85.5mm in bore size
im getting the tune done this Friday to hit 700hp was making sure it was nothing else related

All of this is pointless with the car not being tuned..
A 3582 should spool around 5-5500 on a 2.0L.
