hi there ...

guyz i have 997tt with auto transmmtion
I want to ask the one with experience which is better ..

i allready bought :

1 ) IPD Intake Plenum
2 ) Agency Power headers
3 ) Forge BRV Piston Valves

and maybe i buy a used fabspeed exhaust (( not sure ))

and i take out what in side the cats so the cats is empty now

anyway

still Did not install the mods to the car ..


and i get the softronic flash also


My question is which is btter :

i do the Installation of the mods first then i flash the ecu with softronic ??
or i flash the ecu then install the mods in the car ??



thanks

 

do the exhaust and mufflers first before the flash. I try to do my mods one at a time so I can document/feel the difference with each mod. Personally, I like going thru the stages vs doing it all at once.

 

but am not sure that i will buy the exhaust maybe not

 

for the money and performance gain, (exhaust + flash) is the the best mod for the Turbo. You'd be at about 580hp just with that. Should've bought the exhaust first before getting the BRVs/headers/etc. Next is suspension(coilovers). This is just my opinion.

 

ahaa ok .. i will try that man

is fabspeed good exhaust ??

there are alot of versions ,,, 1 , 2 and 3 ??? are they diffrent in preformance or just the sound ??

 

for the price, yes. Of the newer version Fabpseeds(with HJS cats), there's only V3 and V2. V2 is moderate and V3 is louder. Same performance gain. Only difference is the sound due to the inside of the mufflers.

I believe someone is selling a used one on the board. PM tssci. He's got the V3 and chrome tips for sale.

 

am not lacal , but someone live in my country will sell it ..
so you suggest to me buy exhaust ...

if i did not buy the exhaust ...about my mods i do the flash first ?? or install the mods then the flash ??

 

without the exhaust, just install what you have first then do the flash but I strongly recommend you do the exhaust first before the flash.

 

mmmm i will see what i can do about the exhaust ...

how much whp you the car will get ??? with the mods and the flash ?

 

today i intalled the fabspeed exhaust and the ipd plenuim ...

the car reach just 12-13 psi !!!!!!!!!!! before when it was stock it reach sometime 14 psi ....

now when i put the geer 5th and speeding the car reach 15 psi !!!!!

is this normal ?? because still the ecu not flashed ???

 

That's not normal. You might have a leak somewhere with the new plenum.

 

It's good that you did the exhaust first before the flash. The ECU flash should be tailored to what mods your car has.

Losing boost pressure like that is not normal. There must be a leak somewhere. Check all clamps on the exhasuts and cats. Check the clamps on the plenum (these have a tendency to come lose). Make sure they are secure and not leaking.

 

yes it was a leak in the cats .. today i will fix it

i will update you asap

 

fixed the cats leak ...
waiting softronic tuned map to be send
