jackkelly Posted April 1, 2014 Share Posted April 1, 2014 (edited) My set up is..Speedvision Hybrid CT9 Gen 2WEPR tubular manifoldZ-Sports 38mm external wastegateTial .6 bar springWEPR downpipe2.5" stainless pro racer catbackJAM ECU1.4mm steel headgasketApexi AVC-R at .95 bar boostARC topmount intercoolerCusco bigbore hotpipeNGK Heat range 7 plugsMagnecore 8.8mm leadsOEM king leadMy issue is when I'm on boost, take for example in 4th gear at 4,500 rpm on full throttle the car boosts perfect (holds .95 bar steady) and the revs climb evenly but the car feels like it has no torque (felt more powerful last week at .6 bar)I also noticed if I launch the car in first (have boost by gear set) and it spins in first, catches grip and when I bang second the car bogs down a lot in second gear!!! As in it's spooling perfect and reving perfect on full boost in second gear and it just feels like it's holding back through the revs mental!! Then I hit third and it feels slightly better but not great.If I leave off the throttle the car gives a chug as if it want's to speed up when on 10% throttle.Same in all gears but most noticeable in 5th.I had a problem last week and she threw on code 52 (knock sensor).. I changed that today and the car drove fine but noticed it hesitating again in high revs tonight, not half as bad but still noticeable.I'm thinking because the JAM ecu's main way to fuel the car via the Lambda it could be fucked, throwing too much fuel in and bogging it down???I'm also thinking the ARC top mount could be getting too much heat soak and bogging down the car aswell????I was also thinking it could be a weak fuel pump????Plugs weren't done in over 6 months but I took them out and they look perfect!I got my ignition timing set up two weeks ago.I flash code tested the car and not one fault came up.Any opinions welcome lads, thanks.

richardc9052 Posted April 1, 2014 Share Posted April 1, 2014 (edited) Jack i have a wideband here, if you wanted to fit it and test your car on a few runs your welcome to.. What plugs are you running? Have you changed your fuel filter? Edited April 1, 2014 by richardc9052 Quote Link to post Share on other sites

richardc9052 Posted April 3, 2014 Share Posted April 3, 2014 Are you using a rrfpr? Quote Link to post Share on other sites
triple j Posted April 3, 2014 Share Posted April 3, 2014 Another good point u mentioned there Jack is fuel pump, what pump are u using if it's still the stock one get rid if it. Quote Link to post Share on other sites
jackkelly Posted April 3, 2014 Author Share Posted April 3, 2014 No I'm not using a RRFPR. Everything on the engine bay is standard.Would an uprated fuel pump not fuck up fueling and over fuel it? Quote Link to post Share on other sites
richardc9052 Posted April 3, 2014 Share Posted April 3, 2014 No, you will still have the same pressure in the fuel rail.. thats what the fuel pressure regulator does Quote Link to post Share on other sites
