No problem, probably best to just post your Q's in the forum so others can learn too. VQ tuning is still a relatively new market without a ton of knowledge floating about. At least your tuner knew you needed some basic fuel system mods rather than just go for it and blow up your engine.

 

Just giving an update, I ended up getting the DW 600cc injectors along with the JWT FMU, then EFI Logics tuned my car and it dyno'ed at 304whp at what was supposed to be 5psi. Not what was noticed that I lost boost in the middle of my rpm range and then had it climp back up only seeing 5psi or close at 6k, after which i was told my MAF peaked. With the provided map there is also a starting issue where the car starts rough until i give it gas once and then it clears out and idles. This was tuned with the Cobb Accessport which I am constantly being told is not the best tunning solution for my car being FI. So after driving for a while, i noticed the boost drop as well. I decided toswitch from internal wastegate to a 38mm external one and that change eliminated the boost drop issue right away. I would probably show better numbers on the dyno with the external wastegate. So then the was a problem with afr at idle which was very weird for a while until my alternator died. Installed an new alternator and got to thinking that mayb my idling issue had something to do with the voltage fluxuating at idle. So recently i took out the underdrive crank pulley and installed my stock one back, which actually made the idle alot better, but still not perfect. All in all my car runs very well right now at 5 psi, with a starting problem not as bad as before but still there and throwing a p0300 dtc which is a random misfire that only happens when i start the car, a rich afr condition at very very light throttle (talking like -23 vacuum on the gauge) and the OL/CL switching in every gear at 2800rpm when I'm seeing boost as early as 2200rpm(bigger problem in gears 4-6 then 1-3). So this is where I am now and the next step would be getting a diff tunning device like uprev osiris with the upgraded maf sensor and having EFI Logics retune my car with that as the accessport isn't able to get the issues cleared. Mayb ill add an intercooler as well if its ok with them and see if we can up the boost a bit since the maf will be able to handle it this time. I'll check back in when I know.

 

Honestly dude the issue is with the tuner not the EMS -- your tune is really bad. Cobb is hardly any different than Uprev... both allow modification the same stock ECU tables. My recommendation? Get a new tuner, not a new EMS.
