I recently had a TR 236/230 .599/.575 112lsa cam installed and tuned. car still strugles to find idle alot. Sometime it is great other times it will surge up and down for about 2 minutes. Is this normal with this size cam?

 

most definatly...get a tune and be happy...you will prolly still have surging a little even when tuned..but nothing like what you have now

haha you edited the post on me...that is not normal cause the tune should take care of it

 

That is what I thought to. Sometimes you start it up and it is great others you just want to drive it into a wall. I feel kind of stupid sometimes at a redlight with a loud *** car going waaaaa, waa, waaaaa, waa, waaaaa.

 

i'd get that checked out...where did you get the tune from...that is how my cam acted when it was untuned...and mine is a little bigger than yours

just wondering - what other mods do you have on your car

 

I have forge internals, ls6 intake, ported maf, ported TB, lid, exhaust, stock 98 heads, and it was dyno tuned.Put down 410 hp

 

where at...who did the tuning...do you have a graph...sounds like it was just tuned for wot...no street tune...that's quite a bit of power out of a cam only car...especially with a cam of that size...

 

I will pm you it was a sponsor who did a good job with everything dont want any bad publicity for them.

 

Does it do it when warmed up? Mine will hunt/surge at idle for a couple minutes after startup, longer if cold.
