Power Jet Member 151 Member For: 17y 11d Gender: Male Posted 24/08/10 10:38 AM Share Posted 24/08/10 10:38 AM Hey guys,Before I tell you what's going on I will tell you my mods.Rapid V2.0 cooler setup. 60lb Deka'sWalbro Fuel pumpXForce 3.5in systemValve springs (Newly fitted)I am running on a soft tune 362rwkw at the moment.However,I recently got the car back after the valve springs, the car drove like a... Monster.But now (2 weeks later) is a bit inconsistant. The car pulls hard off the line and at about 4000rpm in 2nd & 3rd (Havent's pushed 4th yet) it feels like I lose all boost and the car goes N/A. It then picks up at 5000rpm and pulls like a freight train and then I change gears (6spd auto).When the car does hook up properly it pulls fuken hard but the car feels like it intermitantly pulls on and off very quickly. Any ideas?Car is a mk1 06 XRT Link to comment https://www.fordxr6turbo.com/forum/topic/70157-losing-power-top-end/ Share on other sites More sharing options...

Sedans suffer fuel surge a fair bit when boosted and flogged!I would take it back to the tuner for some diagnostics.

Power Jet Member 151 Member For: 17y 11d Gender: Male Posted 25/08/10 03:48 AM Author Share Posted 25/08/10 03:48 AM thanks fellas,I dont have the flash box. The tune is Snipered in. But what I should of mentioned is that it is a street tune only as his dyno is in bits at the moment. Either way the wastegate and actuator is booked in because I f*cked my exhaust housing, exhaust had a leak for too long and the gases wore it away a bit. So in 3 weeks its going for machining (exhaust housing) and while the turbo is off. WHY NOT Perhaps that could be it? street tune with no dyno... Good thing he is an experienced ford tuner Link to comment https://www.fordxr6turbo.com/forum/topic/70157-losing-power-top-end/#findComment-1034931 Share on other sites More sharing options...
