whats the specs on that s300?
Sounds like its time for something bigger....
Bump the timing up, that will help. Porting + a manifold will also help. air in and air out = happy EGTs. Any for of an air intake system will help over the stock airbox/filter (flows a measily 140cfm)
Which pump are you running?
