LANCER EVO7

Hi everyone, i have a evo 7 gsr and got a 20g upgrade, Dw 200 fuel pump, exedy clutch stage 2, ic piping upgrade, header, 3 inch exhaust complete no cat converter, hks high flow filter and right now runing at now at 1.4 bar, the redline is at 8.000 rpm before was at 1.6 bar and same redline but i was told that the limit was near but the push is a little less than before, i put 97 oct fuel and speed booster from liqui moly when i get on the track
Im trying to figure out how much the engine can handle before a rod comes out and say hi, my plan is to upgrade the rods sometime at the end of the year also the intake is stock, only has a hks filter , some ppl told me is better the stock box for my set up, the engine has 70k kms
How much i could put on it and if i should change the intake a remap is a must?
I was told that i could be on the 350whp range, but here in chile we dont have dyno for 4wd only 2wd
Sorry for the typing and any replys are welcome
Cheers

Remap is a must. My Evo7 put a rod through the block at 330whp on just an 80 series turbo. Take it easy on those old rods
