    New springs in and some comp cam magnum pushrods.decreased valve lash while we were at it to try get faster spool up on the transbrake. Fitted the wideband to check fueling.first thing we notice cold start was leaner hot idle way leaner in gear idle leaner as in 15-16:1 lean. Took it to the street on 21psi ish don't know exact boost gauge goes to 20psi and 2 bar map only reads 14.7 lol.hit boost 13:1 guess it's stopped a lot of exhaust reversion fitting springs. Totally no traction so few blips on the way home to fit slicks and get the laptop even at 13:1 the avgas keeps it alive with our soft timing of 14 degrees.fitted slicks pulled a plug timing Mark right on the weld of the earth strap. Added fuel and hit it again 12.8:1 full traction on the slicks added a little more dead on 12:1 fueling and just dips into 11s full noise before the limiter traction on slicks was limited lol.went a little richer and started getting a miss coming on boost due to the 14psi limit of the map sensor making 14psi too rich now that we have 21psi rich enough.time to fit the 3 bar map and retune lol.checked plug again timing Mark back to just after the bend where it should be :) drags in two weeks see what she runs now.also found the wastegate starting to crack open at 12psi added a second spring should 60 harder hopefully

    Sounds like a fun ride. Sounds like the springs solved quite a few issues.

    The old girls still running hard got it up at 23psi on 14 degrees making up for a loose converter.we twisted a b&m nitrous hotshot converter and it wouldn't stall up at all was almost like a clutch little bit of throttle and it would stop slipping couldn't get past 1500rpm.fitted a used 6500 rpm hughes converter out of a big cube big block methanol supercharged car that came up cheap.makes launching a breeze roll in hit the transbrake full throttle and it's at max boost near instant but it has put us up past max torque and max hp rpm and cost us a few mph but can roll off the trailor and run 1.5 60s and 10s every pass very easily now instead of battling to get in the lights and get it on boost.
    Also fitting a 1.06 A/r single entry t3 turbine housing on in place of the 0.84 twin scroll to try get rid of some backpressure as every time we add boost max hp rpm moves lower so trying to get some more grunt up higher in the revs .it's currently running 3.08 diff gears and 27" tyres to get our mph back from the loose converter as a bandaid
