Here's the latest . I got tired of waiting on the boost controller and the new water pump and was also seeing my air / fuel ratios going
off scale below 10.1 / 1 (on my new FJO wideband controller) , so I decided to tune up to waste spring pressure of 12 psi .
I ended up limiting my rev's to 6400 rpm and I am now running somthing like 10.5 to 11 psi boost with ratios between 10.5 to 11.2 for now since I dont have my water injection working yet .
Everything was going well untill I hit 6500rpm , my boost spiked from 12.5 psi up to 21 , seems that one of my wastegates was malfunctioning , I have since opened them up , one was only opening partially , I freed it up and sealed them back up , now boost doesnt go past 12 psi when I'm in third gear , I just have to take it past 6.5K and see what happens.
My highest intake temp was 85deg . F on a 32deg day (and thats without W.I. and my cold air setup!!) , and exhaust temps at 1450deg F . max
I think I'll hold for now until I get my water pump at least , I may just sell the boost controller and get another one. The car is quit fast and Violent down low , but performance seems to drop off as I go up in the revs , I can hear the motor asking for more but of course its not getting it since I'm limited to lower rpm's.
I also cancelled the order for the pump that I haven't received yet , seems the deal was too good . As soon as I cancelled they wrote back saying that they did not get ano of the five e mails I sent before and that the 220 psi upgrade only pertains to the 140psi pump thats included in their kit !.
