Hi, I have had great success with my previous flash with you guys..298/310 TTW. Great #'s But now the bug has hit me again and I am after more power. I've recently bought a few goodies and was wondering if installing them would affect my tune in a negitive way.

Perrin boost tube
AMS lower intercooler pipe
Helix O2 housing

Also in the near future I want to change out my exhaust manifold.

My current mods are:
Apex induction box
Helix DP
Helix test pipe
JIC catback
Walbro pump
MBC 21psi
Greddy type S BOV

So wold I have to retune my setup or will it be ok?

 

The first three would not need a retune but the other will.

 

ok, I am swapping out my intercooler next week, will I have to retune for it? Also, how much is a retune if I already go a tune from you, is it the same 450 or do I gt a discount for being a returning customer?
