SkevosEP91 Posted October 19, 2014 Share Posted October 19, 2014 Hello guys and greetings from Cyprus!!!We finished tuning last night and made 279 whp and 313nm of torque!!!The car is on 98octane pump fuel and the engine is a forged 4e with 5e cams and fully stock head!!!Turbo is Vf30 and we boost it at around 1.8 bar but it cant hold boost and it drops it about 1.55 to revlimit!!How can i hold the boost up top to 1.8 so we get close enough to 300whp range???? Also the Ecu is a standalone Adaptronic 440d !!!! Quote Link to post Share on other sites
Matt1878 Posted October 19, 2014 Share Posted October 19, 2014 What boost controller are you running? And what Wastegate? Quote Link to post Share on other sites
AdamB Posted October 19, 2014 Share Posted October 19, 2014 What wastegate spring are you using? If running a soft 0.8 bar or so you will need to change to a stiffer one something like 1.4 bar. Quote Link to post Share on other sites
SkevosEP91 Posted October 19, 2014 Author Share Posted October 19, 2014 We dont have boost controller!!! We have the n75 boost solenoid from an Audi and everything is controlled by the ECU!!! The wastegate is a Turbonetics Evolution and i think the spring is 0.8 or 0.9 but its very stiff !!! you cant push it with your hand !!! Quote Link to post Share on other sites
AdamB Posted October 20, 2014 Share Posted October 20, 2014 Change the spring to a 1.2 or 1.4 bar spring. Makes no difference whether you can push it or not, the force the air will exert on it will be more than you could ever provide. Quote Link to post Share on other sites
Gainzy Posted October 20, 2014 Share Posted October 20, 2014 As above buy a different spring, a good ebc will do all the work from there! Quote Link to post Share on other sites
SkevosEP91 Posted October 20, 2014 Author Share Posted October 20, 2014 Thanks for the replies !!I will change the spring and will go again for a map !!!Hopefully the car will perform better!! Thanks again!!! Quote Link to post Share on other sites
