hey guys.
my auto cefiro (soon to be manual) has gotten slower it seems lately, and especially struggles up hills. it revs and spools fine (14psi on stock turbo on RB20) but just doesnt seem to get anywhere. i put some big sucker wheels on it just yesterday and took it for a drive, came out of a corner booted it the turbo spooled but the car far from took off, then its like the auto grabbed and spit the car sideways and then shot off.
im not really sure what it is but any info or ideas would be great.
cheers
