Catless divorced DP with Cobb stage 2?

[EJ257]

Catless will more than likely over boost on Cobb OTS maps. Mine did. Just pro tune and be done with it.

It depends on the type of "overboost" you're referring to. A boost spike can be tuned out with the WGDC/TD/Comp tables, while boost creep cannot.

I plan on it when I get some extra cash. Just want to make sure I can run the dp in the the meantime because I have it and the ap. Thanks for the responses all.

perhaps the bugeyes are more forgiving. because my friends '02 wrx is running a Cobb OTS stage 2 map and a full catless turboback. no problems, no issues, its not running lean or boost spiking in any way. not saying its the right thing to do but it pulls hard and smooth with no ill effect for the last few years that he's had it

Bugeyes are more forgiving, you don't even need a tune to safely run a TBE.. that, and Cobb stage two maps for those years are designed for use with catless exhausts. Also you have to cinsider the fact that boost creep is a direct result of the wastegate not flowing enough to bypass the turbo, and 02-07 WRXs come with a completely different turbo, wastegate included.

Overboost codes are common, although I would be more concerned with the knock associated with over boosting than the code itself.

This is what I was going to say. I had this problem. I was getting 3-4 counts of knock. It didn't matter with map I used LWG/SLWG, they all over boosted and knocked. I had to get a protune. That was my only option.

I don't think it's a good idea to run those OTS maps with a catless TBE; whether the cat is in the DP or custom put else where.
