hi guys 

my blob sti PPP went for a rolling road day at area 52 in nottingham.  the results weren't good.  car came in at 269bhp.  i was expecting alot more than that!!! what could be the issue.  the car is stock apart from a cosworth panel filter and a gfb BOV.

dont know where to start looking.  please help

 

 

Hi well just a quick look and if that’s your reg on the top middle that is showing that it’s an sti with BHP from factory at 261.5. So by that I’m unsure if yours is a ppp. If it is do you have the certificate to prove it is? And if standard car then 269 is, with just a panel filter and age of car, I think your doing good.

I haven't seen many standard graphs but that's eitherca conservative oe map or it looks like something is holding it back after 4k .
If it has avcs is it working ok , how does the car feel to drive ?

hi guys,

 

a quick update.  took my car to TDR in Coventry for a dyno run with a health check.  he found that the waste gate spring was a little weak (due to the age). a quick tweek and voila.

288bhp!!
