boost return mod

ive just done this mod and my engine is running like poop, got the gt inlet and dewedged tb, r1 charger but cant get it running nice, put the boost return back on, minus the breather to stop crap in the charger (blocked the breather hoses) but no change, no map yet but jus wondered if there was a technique to home tuning till i have run the charger in and rr tuned

did you do the boost return at the same time as the dewedged TB? Specifically how is it running like 'poop'? Just different feel to driving or an actual engine problem?

Dont spray for 10 secs though. Maybe 2 secs.

Indeed! Spraying for 10 seconds is really bad advice, it's this reason that people find all this excessive build up of PTFE gunge in chargers. Like Jez say, 2 seconds is about right. I used to give mine a few short (maybe 1/2 second) bursts.

engine not running right is something wrong, not the boost return mod or needing a remap. Is the ignition timing right? Although like hardchargin says, need more info really.

ignition is spot on, i believe its the wank chip prev owner put in thats mashing up the air waves, runs great till you put ur foot to the floor then it runs outa puff, little bit of boost but its not sending me up the road like a roket, evan with a blown charger b4 i sent it away it was faster, its defo over fueling tho, i can smell it, and my poket can feel it lol,, wat dya recon, im nearly at the required milleage to give it a proper blast past 4000rpm then goin to see san speed to get a diagnosis and a tune hopefully,cheers guys

also its not chugging or anything, the delivery is still smooth but without the g smiles or head stuck in the seat values

ISV pipe disconnected from boost hose - boost leak. Have you got a boost gauge? Probably boosting 0.4bar if thats disconnected or leaking.

That or an overfuel, could be chip if did it before aswell - you haven't changed your injectors have you? Running greens for instance without the corresponding map would overfuel it causing chuff all torque and power and be very thirsty without having running problems.

i had a gt injector rail on it, so i put the g one back on still with yellows on it and i have the g smiles again, i think its defo time for a map, boosting well now, wat do people think of san speed in bexleyheath, no boostleaks it was jus fueling wrong but now its gravey again, is a custom map th route to go or just generic
