Hey fellas, I have a 08 MR that was running a Perrin 93 stage 1 stock for the longest time and I finally decided to take the plunge and start modding.

So far I have a Greddy SP catback (2.75"), Milspec hi flow cat, Cosworth drop in filter, AMS UICP while running Cobb stage 2 93 PF map. After hearing about overboost with the regular map I was running a LWG map. Today I ran the regular map and had a max boost of 25psi as intended.

My question is what I should do next? This is a DD and of course I prefer to have it run reliably, but was wondering if I can get to 300 to 350 at the wheels with just a dyno tune. Are there any other bolt ons that u guys might suggest before I take it to the dyno? I also have a Grimmspeed 3 port controller, but I have a buddy that tells me it's not necessary.

Also, I'm in the chicago burbs and I think there are a couple of tuners in the area including AMS and Boostin Performance. Any recommendations?

Thx in advance.

 

Use the GS 3-port once you go get custom tuned. How about an upgraded intercooler and/or o2 elim downpipe? You could go to a full intake too rather than just a drop-in. Since AMS is local to you I'd probably go there, they can protune your Accessport.

 

Tune for sure.

 

O2 housing / downpipe eliminator would be a good mod. A full intake instead of just a drop-in would also be nice.

Then most definitely a tune.
