xe with let injectors, bogging abit?

[ReeceH]

got a standard xe corsa, and its had let injectors fitted and a 3bar fpr.

it seems to bog down at about 5k revs, now of course am thinking overfueling, wondering what best thing to do is? put standard injectors and fpr on or is there summit to you can do to stop it overfueling and run sweet?

[BIGS]

just swap it all over then sell the let ones on

[ReeceH]

aye think thats me plan like.

[Rexy]

what colour are the injectors?

[Stuart]

clean and fit std XE injectors. Then refit the std FPR and it will be fine.

More fuel = boggy running (without the extra air of course).

[ReeceH]

nice one! thats what i thought like. shall swap em over today then sell the turbo ones

The standard fuelling arrangements on MPi Vauxhall engines can typically cope with upto a 20% increase in power without the need for bigger injectors etc.

Its just a common misconception that more fuel = more power.
Borewash doesnt win races.

some xe's come with 3bar fpr so if you get the injectors from that you dont need to change the fpr

Personally I'd run with what the engine/ECU should have.
