performance question

[egraffy at earthlink.net (Carpenter/Graffy)]

Thanks for getting back to me, Brian.
You mentioned the 84 GTI fuel distributor combined with air shrouded 
injectors and a simple mechanical advance ignition distributor , along with 
your recommendation for the 272 cam. I have driven 87 GLI's and GTI's with 
this motor and the stock cam and ignition system, and have not experienced 
the performance limitations I did today. Although I agree that the engine 
could use a more aggressive cam profile, I have to believe there is 
something more basic going on here. In addition, I was experiencing this on 
long straights, which would rule out anything related to differentials. I 
have no problem with corners.
Thanks Again,
Cris
