Hey Guys,

I just got a new boost controller, nistune and a walbro fuel pump installed today.

Once I warmed the car up and started driving it I have realized that there is a bit of a problem, when I take off the car is jittery? its like the power is cutting in and out, but once I am above 2k - 2.4k rpm the problem is gone.

The car is also idling a little lower and a little rougher. If I hold the revs at around 1.5k rpm the revs will slightly fluctuate and even though I am slightly accelerating it will continue to fluctuate revs around 1.5k rpm until i have accelerated enough that it goes up straight to around 2.5 - 3k rpm.

Does anyone know what the problem could be? or ever run into this problem? The car was running fine before and has new splitfire coilpacks.

Thanks a lot for any help.

Mate just do the fuel pump rewire, Im sure that will rid u of the problems- mine was running like arse at and below 3200ish rpms, jerking, power loss, idle and startup was crap, blowing a bit of smoke at low revs sometimes, when Jez rewired the pump to get direct 12V, it was a different car altogether

    • As GTS mentioned, it takes a bit of faffing, some fiddling and a little modifying.  With the strainers, you can buy different styles. Some sit flat on the pump, some angle down.  Here are some photos of mine, ignore the ugly welds lol. 
    • The smart thing is to actually locate the pump at the right point down the hanger, so that the strainer can stay sticking out at a right angle, but near the bottom. This is the perpetual hassle with retrofitting any different pump to the factory hanger. Some just go where you need it to, some need fiddling and faffing, and modifying of stuff.
    • Some updates. After a lot of praying and some inspecting of crank threads, we've found that they were both kinda munted but nothing seemed terminal. The other option was drilling and helicoiling the crank. That is obviously the last option so we decided to at least try to get a OEM GM bolt in to GM Specs. So after honing/linishing the balancer from it's .002" interference fit to a .0018" to .0015" to .0013" it eventually slotted on to the crank. ATI state the interference is nominally 0.0007-0.0009... so it's still snugger than ATI reckon and explains the issues we had to fit the thing to begin with. New GM bolt went in at 37 ft/lb then torqued 140 degrees after which was EXTREMELY   but it tightened up to 140 degrees and it was a lot of force. So all things considered, the balancer is secured to the exact specs that GM want with the OEM Stretch bolt, (that ATI say you can use..) and the balancer itself is seated and snug AF. So WOO. Engine is now back in the car with lots of swearing. Bellhousing bolts done up, driver side manifold is on, AC Compressor and hard lines are back on the car. Next step will be to connect various engine bits/wiring/intake/radiator etc. Then oil and coolant and ... test start it? And of course, looking into this issue... which actually doesn't look so bad - It looks like it can be twisted back into shape with a set of multigrips. Anyone wanna buy my bonnet? Boy it looks good over there and sunk cost sucks.
    • Also this may be a stupid question, but how would you recommend getting the strainer on a downwards angle ? as they tend to obviously clip to the bottom of the pump which usually sits level 🥴
