no no no no.

i was like yourself when i 1st got my fiesta. it had a t2 hybrid on it, running 12psi, got to know a lad who had a stage 1 t3 on it, he was runnin 9psi iirc on a bleed valve. both standard engines etc etc

he took me out in his, and then i got to drive it myself, and i must admit, mine felt alot quicker. boost came on quicker

i said to him mine felt quicker, and he disagreed. we went heads up on a disused car park, and he truely spanked me

so since then, t3 all the way, it does not fell as quick, but when the boost kicks in, you certainly know about it. pulls harder, and for longer in the rev range.

no doubts about it. end of discussion
