More HP available?

[CountySoldier]

Any input on more HP in my engine with the mods listed below? I did NOT have my tune modded after my Apten install. I wanted to hit closer to 500hp. Should I see if James from RWTD can find some more HP? Or do I need a throttle body?

your hp is outstanding though!!! i think with Cats'' you may get little more...

I did feel like I lost TQ after my x-haust....maybe its loss of back pressure?

my tuner recommends cats

I have plenty of fuel available, think I can give it some more timing??

Does a new tune usually go with an Apten install? Anyone know?

I remember reading that a tune went with the apten, because I was wondering about the apten mod, but with stock tune & pulley. People said the car would have to be retuned:shrug:

I guess I need to get with RWTD!!!

I re-tune after every major mod just to be on the safe side. The last thing I need is a blown up $13K motor over a $500 mod.
