Hi Guys
I am running a 1994 J Spec T88 Supra... have just had new 850cc injectors and a New V PRO and remap
But whilst mapping the car it appeared we had a major boost problem
At .8 Bar /5.5rpm it would almost cause a cut..and would effectivly kill the car.. the lads mapping it said it was the boost controller ..and i should go aay and have aplay with the setup..
So first thing i did was plump the Wastegate in direct (have a Greddy External Unit) so left top port venting and plumed the side port into a boost pressure feed.. have tried from both mnaifold and intercooler pipe..
Initally felt very good..would rev out fully BUT would only create .4/.5 bar and sounded liek the screamer pipe was working very early and dumping all pressure..
Have tried playing about with the boost controller, have read throught the manual , but doesnt give much info..have tried with feeds form 2 places ( manifold and intercooler)..and checked allpiping ,all fine.. but boost feels stonger but still get this "CUT" ....have spoken to the lads mapping the car and say it has no cuts mappd into the map.
Has anybody got any ideas on what i could try next..Because im a bit stumpted.... is there any thing else i can try??
BTW..amd running a Profec Boost Controller as fitted in Japan..also all work was carried out in japan except the injectors and new ecu and map...
Hope some one can help
Cheers
