I have a Greddy SP2 Catback and K&N Panel Filter, plus a boost gauge. I also have Al's (Dynoflash) E-tune which was based off these 2 mods ready to write to my ECU once get I my MBC on. My question, he tuned me for 22 psi tapering to 16 based on these two mods, can I set my MBC to run 20 psi daily and crank it to 22 psi for track use? Should I keep set at 22 psi for optimal tuning/driveability? Lastly, I'm getting a DC Sports Downpipe/Test Pipe combo this week...do I need a reflash? Or can I install it and will be leaving a few ponies on the table. Thanks!

 

Bump anyone?

 

can you run less psi? sure you can it's an e-tune the parameters aren't going to be perfect running less boost is safer

the dp and test pipe free up a lot of flow...you are only hurting performance by not getting a new flash...watch your boost gauge the extra breathing room will make your turbo want to boost more

 

i think you should do your mods, then get reflashed for them. Thats the best a safest approach
