1. Took it for a runting to the Esex meet and it holds it's 5psi lovely if you razz it up through the gears. However if you hold it steady and boot it in 4th or 5th it just overboosts and cuts out Any ideas before I make it something else for the SCC lads to look at?

2. Are the TPS the same on OFAC as on OFAB as mine may be iffy and a mate is breaking an OFAB managed car.

CheeRS in advance as always

 

i thought ofac and ofab was different? could be wrong dude

 

Only difference from OFAC to OFAB is the Map sensor. Otherwise they're the same.

 

And of course the ecu!

 

i changed mine on my OFAC managed car and made no difference. still have the old one lying around and i guess in perfect working order if you want me to send it down?
