got some bad news. well its not bad. but for the time frame its bad. ill explain as best as i can.
the car on the dyno was tuned with 100oct 40psi with a BR double pumper and 1200cc injectors. on the dyno with the FF intake we saw 90% duty on the injectors. sean knew the FF intake would make a difference on the street so after around 100mph he has the FCON set to add 2% more fuel.
anyways i took the car out on the road today to make sure all is well for sundays track day. 1st 2nd and 3rd gear are retarded. but once i hit top of 3rd and shift into 4th the car begins to get very lean. on the dyno it was in the 11.6/8 afr range. 4th gear up to 7000 rpm ''cause thats where i got out of it'' i am showing 12.5 AFR. so i spoke to sean and he thinks the FF intake is causing it to go even leaner. which makes sense because the force of air on the road is much greater then on the dyno. he said to lower the boost a few psi and see what happens. it gets better with less boost and at about 35psi it runs strong. but this wont cut it for are 9 second goal.
so in the mean time i pulled the pumps out and pushed the reliefs down to get more out of the pumps. i am hoping this will help. ill find out tomorrow when i take the car out. what do you guys think???
if that does not help then ill be running sunday with 35psi. which is ok with me because i want to get a good feel for the car, clutch and launch. i just dont think ill be ripping a 9 second pass. if i can i will be getting the ID2000 injectors this week and if sean has time a retune with them in. i think this time we need a highway and not a dyno. HAHA.

i just called STM to place an order on a FPR kit and fuel line's. i got to call back in a half hour to talk to Emery.
i am trying to find info on the aeromotive 340 intank pumps as i want to buy 2 fuel pumps that flow more then the walbro 255's.
also i need to order ID2000 injectors. i think after this is all fixed up i will not need anything ever again. i hope not
