I do recommend an intercooler with that map

And that's with an ewg model jb4 too correct? And is the inter cooler urgent or can I do it later on the road? Is it going to heat up that bad that I would need a aftermarket one Instead of the stock for daily driving and sometimes hard driving? Thanks for the help Mike

I would not say it is urgent as no damages will be done with the stock one
But even with daily driving after couple pulls you will lose power with the stock intercooler which is why we recommend upgrading to a better aftermarket one

Map 2 EWG will give you +6 psi over stock vs map 1 + 4

Yeah I will be sure to make an order with you for that real soon then.

So I shouldn't use map 2 EWG since stock 18 psi with the additional +6 will go to 24 psi?

.. While I want to stay at 22psi max for safety drive reliability , you recommend using map 1 with the cateless down dps instead? Since it will be 22 psi instead of map 2 at 24 psi.

With the N20/N26 i always recommend staying with map 1 for daily driving

I've been wanting to do this for a while but I have read some posts about peoples engines blowing up when they have these two installed on their car because the N20 might not be strong enough to handle all the extra power. My car has 28k miles, I only put 93 gas in it, and I'm sure the warranty is about to expire in a few weeks. Let me know what you guys think!

As long as you run the recommended maps with the correct fuel you will be fine.

Keep boost at 21-22psi

Map 0: JB4 disabled.
Map 1: PWG models absolute target 21psi peak, EWG models additive 4psi peak over stock.
Map 2: PWG models absolute target 22psi peak, EWG models additive 6psi peak over stock.
Map 3: Progressive Methanol Injection. Requires BMS methanol kit or BMS FSB for meth pump control.
Map 4: Stock performance, JB4 on
Map 5: Absolute targeting map with a peak boost 17psi. Suitable for 320 & 520 applications.
Map 6: User definable absolute target map. Suggested for troubleshooting by professionals only.
Map 7: Race gas absolute target map. Peak boost 23psi. This is a fairly aggressive map and increases engine damage risk. Use with caution.

Which down pipe do you recommend, Wagner or Evolution Racewerk? I know the ER down pipe has a flex zone which I have seen people recommend and I'm honestly not sure if the Wagner has one or not. Do you know if the Wager has a flex zone or does it not matter whether or not it has one?
