Exhaust and remap
Hi all
I am having a millitek 3inch system with a 100 cell sport cat fitted tomorrow but JGM can't get me in for a remap until the end pf January, will this be ok to drive until then without the map?

Im not sure its going to be very happy with the sports cat on, the exhaust should be ok but the free flowing sports cat may cause boost spikes, especially in this weather, I personally wouldnt do it until closer to the day you have your remap.

Is it the Powerstation system with the de-cat down pipe and cat in the mid section because if so it flows so close to a full de-cat that you may well have issues with boost control.
You could bypass the boost solenoid and run on actuator pressure only to be safe.

The miltek sports cat is very free flowing and works almost identically to a full decat.
Needs mapping asap or driving off boost.
or ...
A good makeshift solution would be to connect the turbo to the wastegate to ensure you only get wastegate pressure til mapped - that way you can still enjoy driving it but with no danger of overboost/boost spikes. Remove the existing T piece from the turbo and actuator and fit a straight vacuum hose between the two. JGM can always refit the t piece for you at mapping time.

Engine can det and that can damage the piston or lead to engine failure in the worst case,

Thanks for the advice guys, I had the exhaust fitted today and it sounds fantastic , not too loud but a nice little rumble, no lights have come on yet, though I have not taken it above 4500 revs, I have also moved the mapping date forward to the 13th Jan.

Are you going for an Ecutek Megarom remap with proper twin maps, in gear boost control etc?
My Spec C when I had it had the standard Ecutek remap but when Bob Rawle remapped it for me I had the Megarom remap and it made a real difference to in gear acceleration and the driveability.
Good choice on the Milltek by the way.

It is worth doing as the in gear boost is properly setup to your selected gear and engine load.
As far as I'm concerned there are no cons and if your going to get it mapped then personally I'd go for the Megarom remap, and it helped as well that Bob Rawle helped develop the Megarom mapping along with Ecutek (plus I think he's the chosen RaceRom development mapper as well).

Yes but I left him two messages and missed called him three times without reply, whereas Simon at JGM called back the same day and has answered emails within the hour, and as far as I am aware JGM are very good?

JGM has an excellent reputation and the only reason that I plumbed for Bob was distance and I had my first Impreza mapped by him on another group buy so I already knew him.
I know Bob has spent a lot of time recently mapping out of the country but I always contact him via email and usually get an an answer within 24 hours.
