2008 Spec B first Pro tune issues?

So havnt posted in years, but I still own my Spec B I bought new. This last couple months I finally did some power upgrades when the stock downpipe rusted in two. So now I have a Cobb catted DP to back up the SPT V2 cat back I bought....10 years ago lol. Then I bought a Grimmspeed stage 1, but held off installing it until I could get it on in to the local Subaru speed shop. I read Grimmspeeds original post about there intakes and was afraid of running lean, even with the Cobb OTS stage 2 map.

 

In to the Dyno it went, where it made 230whp and 290lb/ft. Which seems fine, and totally in line with what others see. However driving it I hear pops now during shifts when in Sport and accelerating brisk to hard. In Intel it stutters slightly on hills, which it hasnt done since I put a OTS Stage 1 on it years ago.

 

Never had a car dyno tuned before, no idea on the etiquette. Is this a shitty tune? Do you take it back to them and tell them to fix it? Is it 12 year old parts I need to start replacing (101k miles BTW, lots of sitting while I was on deployments) or do I need to contact Cryotune for some e-tune help?

Very interested in replies!

I'd go back to the tuner and explain what you say here, at your mod level I've never had any of my subarus do that.

Any dash lights on? It sounds as though the tune isn't right but could also be a silly vacuum line, etc. Take it back, that's why you paid them for the install and tune.

I would bring it back to the tuner, you pay them to make things better not worse.

Ha, no. My three vehicles are all last model year for the body style. I have a 2002 Dodge 2500 Cummins, 1993 Mustang coupe and of course the 2009 LGT. You are not the first to ask that....maybe I should clarify!
