Hiya,

Wondered if anyone could answer my query?.....

Bought a 4wd sierra cossie earlier this month; stage 3, MSD 380+ chip to run with Siemens 55lb's and stg3 T34.....

It hadn't been set-up so took it to a local garage. Basically they fitted a manual boost controller to adjust the boost but shoudn't the remapped chip automatically run approx. 30psi boost through the amal? Before they installed the manual boost controller it peaked at approx. only 1bar?

Any ideas why this would be?

CheerRS,

Chris
