You won't get 80whp from a tune on a 335, not without a full exhaust or meth.
335 is not some magic car that defies laws of physics.
Here is a tuned 135 vs stock.
tuned 5.0 will rape 99% of all 335's.
My friend's tuned E92 M3 puts down 360whp. Tunes do barely anything on a E92.
Most tuned 5.0's will be around 400whp and will destroy both the E92 the 135 and the 335.
