I'm having a little problem with boost creep in the higher gears (3-5). I was wondering if getting an aftermarket (Grimmspeed) boost control solenoid will put an end to this??? Any help would be greatly appreciated!! I am currently running a custom tune and have an up pipe and full 3 1/2 turbo back exhaust, stock turbo, stock boost control solenoid..

If you do make the change to any different boost controller, you will need to be re-tuned.

This is probably a good question for your tuner to be honest. It could help. or maybe a ebcs/mbs set-up would be best.

When it is cold out (pro-tip: its December) most turbo cars will overboost even if you have parts designed by Shelby himself and a tune by Jesus.

I have a '05 WRX Stage 2 + EL headers + Grimmspeed EBCS and I still have boost creep in 4th and 5th.

Car was tuned by Tim Bailey too. He sent me some revised maps after the dyno tune in an effort to dial it out, but ultimately attributed it to the shortcomings of the ECU and the stock wastegate in the TD04 (stock turbo).

Just keep an eye on your boost gauge or go with an external wastegate setup.
